Job Locations and Reviews
I replaced the main shutoff valve and installed a new Pressure Reducing Valve to ensure optimal water pressure throughout the system. I also addressed a leaking 1/2 shutoff valve connected to a hose bib by removing the faulty valve and installing a new one. This not only resolved the leak but also improved the overall functionality and safety of the plumbing system.
I successfully installed a customer-provided garbage disposal unit, ensuring it was securely connected to the existing plumbing system. Additionally, I replaced the fill valve in the upstairs bathroom, carefully disassembling the old valve and installing the new one to guarantee proper water flow and functionality. The job was completed efficiently, with attention to detail to ensure everything operates smoothly.
I replaced the hose on the mop faucet leading to the soap dispenser with a high-temperature hose. After discussing with Manager Samantha, it was determined that the line from the wall mount diverter needs replacement. I installed a brass hose adapter and a 3’ washer hose. Samantha will order and install the new wall mount diverter. I signed for Samantha to confirm the work completed.
Upon receiving the customer's request, I promptly coordinated the delivery of a new garbage disposal unit. Once the disposal arrived, I returned to the site to begin the installation process. First, I ensured that the power to the disposal was turned off at the circuit breaker to maintain safety. Next, I removed the old disposal unit, carefully disconnecting it from the plumbing and electrical connections. After confirming that the new disposal was in good condition, I connected it to the plumbing and electrical systems, ensuring all connections were secure and leak-proof. Finally, I tested the disposal to confirm it was functioning correctly before completing the installation. The customer was pleased with the efficient and professional service provided.
On the specified date, I addressed issues with both hand sink faucets, which were producing water from a 0.5 aerator on a sensor with a mixing valve underneath each sink. The water heater and recirculating pump were found in the mop closet, but the pump was not functioning. The thermostat sensor was staged on the hot line and had never turned on because the pipe temperature was consistently above the cycle temperature. I corrected this by moving the thermostat wire to the mixed line. Additionally, the faucets lacked sufficient pull at 0.5 gpm, causing the mixing valve to be set too low. After adjustments, the temperature was restored to proper levels. The first restroom faucet was leaking from the spout at all times, requiring disassembly and cleaning of the solenoid to restore functionality.
Recently, I completed a comprehensive home service that involved a thorough assessment and repair of the HVAC system. Upon arrival, I conducted a detailed inspection to identify issues and provide an accurate estimate. The work included replacing a faulty thermostat, cleaning and servicing the air conditioning unit, and ensuring all components were functioning optimally. I also addressed minor electrical issues related to the system. Throughout the process, I maintained clear communication with the client, explaining each step and the importance of the repairs. The final result was a fully operational HVAC system, providing enhanced comfort and efficiency.
Upon inspection, the ADA toilet in the women's restroom was experiencing slow and weak flushing. I disassembled the toilet and replaced the diaphragm with a new one. After reassembly, I turned the water back on and observed that the control stop, when fully open, caused the toilet to spray. To resolve this, I adjusted the control stop to a position that prevented spraying while ensuring the toilet flushed correctly. I informed the manager about the potential issue and advised that if the problem recurs, a technician should be called to replace the control stop. Currently, the toilet operates without leaks or further issues.
Upon receiving a call about a clogged laundry box, I promptly arrived at the site equipped with specialized drain tools. Upon inspection, I identified the blockage source and proceeded to use a combination of manual and mechanical drain cleaning equipment. The clog was stubborn, requiring multiple passes with a drain auger to fully dislodge the obstruction. After successfully clearing the blockage, I flushed the drain with water to ensure smooth flow and checked for any signs of residual debris. The job was completed efficiently, restoring proper drainage and ensuring the laundry box was fully functional. Throughout the process, I maintained a professional demeanor and ensured the area was left clean and tidy.
Upon inspection, I identified a leak in the hose connected to the mop faucet, caused by a hole in the hose. To resolve this issue, I promptly replaced the damaged hose with a new 3-foot garden hose, ensuring it was securely attached to the faucet. This repair restored the faucet's functionality, allowing for efficient use. I verified that the new hose was properly installed and tested the faucet to confirm its readiness for use. The customer, Anthony, was informed of the completed work and expressed satisfaction with the repair.
30am. Given the timeline, we decided to return the next evening to replace the floor sink. On 9/16, we excavated the old floor sink, removed it, and installed a new one. We then poured quick-dry concrete, backfilled the area, and cleaned up. The soft rubber floor is now ready for repair. Parts used included a 12x12” floor sink, a 1/2 grate, and a bag of quick-dry concrete.
Estimate sent
Upon arrival, I discovered a significant puddle near a hose bib. After thorough inspection, I confirmed that the hose bib was completely dry and not leaking. I then knocked on the door of unit #304 and spoke with the tenant, who informed me that they had already reported the issue. I examined the area and the tenant explained that the area had previously flooded, prompting them to remove nearby bushes, redirect gutter drains, and lay down pine straw. I advised the tenant that the issue likely wasn't stemming from the hose bib, suggesting it could be a drainage problem or frequent use by passersby.
Upon inspection, I identified a leak originating from the left side Franklin drain seal. I removed the gasket and installed a new one, followed by resetting the lock ring. After testing, I moved to the right component and discovered a broken Franklin drain handle. I replaced it with a new handle. On the left side component, I found the handle lock nut to be loose, which I tightened to the correct specification. I also checked the o-rings on all three component plungers and tested them. Additionally, I found a broken lock ring on the spout, which I replaced with a new one. I conducted thorough testing of all components. The manager, Erica, was present and tested the components' ability to hold water before I departed.
On 9/9/26, I addressed a restroom issue involving two toilets. One toilet had a broken seat and a non-functioning fill valve, while the other was fully operational. To resolve the problem, I switched the good toilet seat to the functioning toilet, leaving one toilet with two issues. I replaced the broken toilet seat with an oblong covered no-slam/slow-close model for a quieter and smoother operation. Additionally, I installed a new fill valve to ensure proper water flow and efficient flushing. The job was completed successfully, restoring full functionality to the restroom.
On 9/8/26, I addressed an issue with the handicap toilet in the women's restroom. The toilet was leaking due to a faulty stop valve that wouldn't hold a seal. After considerable effort, I managed to partially close the valve. Upon inspection, I discovered that the rubber gasket had detached from the plunger and was obstructing the valve. I removed the rubber piece and reassembled the valve. The toilet now flushes correctly and maintains a seal. However, I anticipate needing to replace the stop valve during future maintenance.
On September 8, I was tasked with addressing an issue reported by the shift lead. Three commercial floor sinks had overflowed on Sunday night while the team was emptying them. The manager explained that the drains held water for about 20 minutes before suddenly draining, causing a cleanup of the overflow. Although the issue hadn't recurred, they wanted to ensure it wasn't due to the grease trap again. I began by inspecting the grease trap, which appeared to be at the correct level with no signs of backup. Inside, I filled each of the three commercial sinks and drained them using the mop sink, observing no signs of backup. Returning to the grease trap, I opened the lid and found no rise in the level, indicating that it was effectively managing the store's drainage.
On September 8, I addressed an issue with the Rhino rinse on bar 1, which was found to be loose from underneath. I began by inspecting the mount nut to determine the cause of the looseness. After confirming that the seal was compromised, I tightened the mount nut to secure the Rhino rinse firmly in place. This action not only locked the seal but also eliminated any wiggle, ensuring the equipment was stable and functional. The task was completed efficiently, maintaining the operational integrity of the bar area.
On September 8, I was tasked with addressing an issue with the Rhino rinse on bar 1. Upon inspection, I found that the rinse had become loose from its mounting position, causing a potential seal failure. To rectify this, I first examined the mount nut securing the rinse to the bar. After confirming the looseness, I carefully tightened the mount nut, ensuring it was snug and secure. This action effectively locked the rinse in place, stopping any wiggling and restoring the seal. The job was completed efficiently, ensuring the rinse operates correctly and maintains its integrity.
Upon inspection, I identified a significant leak on the main water line, which was traced back to the irrigation system. After a thorough examination, I determined that the issue required specialized attention beyond my usual scope. I advised the homeowner to contact a professional irrigation company to address the repair. I provided detailed information about the leak's location and severity, ensuring the homeowner understood the urgency. I also offered to assist in coordinating with the irrigation company if needed.
Upon inspection, the pressure relief valve was confirmed to be new and correctly set at 70 PSI. The water heater, however, is a decade old and is causing hot water flow restrictions when multiple fixtures are used simultaneously. I advised the agent to discuss the potential replacement of the water heater with the buyer and to inform us if further services are required. This ensures optimal performance and safety.
Upon receiving a report of a persistent moisture issue, I initiated the process by contacting a specialized leak detection service. Utilizing advanced equipment, we meticulously scanned the area to pinpoint the exact location of the leak beneath the slab. After thorough analysis, we identified the source of the leak. This precise detection allowed for effective planning and execution of the repair process, ensuring minimal disruption and a lasting solution to the problem.
On September 3, I addressed a clogged toilet in the restroom. I used a toilet auger to dislodge the obstruction and then opened the drainline to ensure proper flow. The issue was resolved efficiently, and the restroom was restored to full functionality.
Upon arrival, I inspected the cold water tap drain, which was found to be clogged. I utilized compressed air to effectively remove the obstruction. Following this, I flushed the drain with several buckets of hot water to ensure it was clear and functioning properly. The Gallo cartridge was used during the process. The drain is now free of clogs and operating smoothly.
Upon arrival, I identified a suitable spot for the new 10-gallon heater above the men’s bathroom. I installed the heater on a custom-modified stand to ensure proper water drainage. I connected the necessary copper and PVC piping, including 3/4” FIP and MIP copper pipes, ball valves, and bushings. I checked for leaks and found none. The heater is currently without power, pending the installation of an outlet. All parts were used as specified.
During the inspection, I examined the tankless heaters, which included models 240A and 240S. I also assessed the newly installed holding tank and the hot water system. I discovered that the heaters were experiencing a conflict with the pump due to an internal switch, which I promptly corrected. Additionally, I found that the faucets were not delivering the correct temperature, with some being too hot and others not reaching the desired temperature. Photos of the systems and the corrections made have been uploaded to the app for reference.
If you’re looking for a good plumber BDS Is the best! I decided to go with them because of the ratings which were all five star. I’m glad I did! They are professional, dependable and friendly. The morning I called them they came out that day at the exact time they said they would be there. They gave me their quote before they started the work and stuck to it, and spent extra time on the job to assess more damage. I expected I would be charged more but was not. I highly recommend BDS plumbing. They are family owned and operated. They exceeded my expectations!😊👍
Greg was extremely poised and professional. He did a fantastic job. Thanks Greg very much.
Greg was so helpful! I appreciate his knowledge.
Plumbing in Cumming, GA: What We See Most
Cumming sits in Forsyth County, wrapped around the south and east side of Lake Lanier, and that geography drives most of what we get called out for. The housing is unusually varied for a single city: older cottages and long-held properties close to the water, subdivisions from the late 1990s onward filling the ground between them, and new construction still going up. Plumbing on a 1970s lake place and plumbing in a house finished last year fail in completely different ways.
The newer houses are big, and size is its own problem. Two water heaters, four or five full baths, and long branch runs mean the far end of the house waits a long time for hot water and wastes a lot getting it. Tankless units are common in this construction, and they need an annual flush to keep the heat exchanger clear — skipped flushes are one of the most common reasons a fairly new unit starts short-cycling or throwing error codes.
Closer to Lanier, the lots slope and the basements are cut into that slope, which puts a sump pump in charge of keeping a finished lower level dry. Freezes take out hose bibbs and irrigation on the water-facing side of the house, where nobody thinks to shut them down. And parts of Forsyth County outside the water system run on private wells, which brings iron staining, sediment and hardness that shortens the life of anything the water passes through.
Our Most-Requested Services in Cumming
- Tankless Water Heaters — the standard in a lot of newer Cumming construction, and a common upgrade in remodels.
- Tankless Flush Service — the annual descaling that keeps a tankless unit from short-cycling or faulting.
- Sump Pumps — finished daylight basements on the slopes running down toward Lake Lanier.
- HALO Water Filtration — iron, hardness and staining on Forsyth County properties served by a private well.
- Hose Bibb Repair & Replacement — outdoor faucets on the lake-facing side that split in a hard freeze.
- Water Heaters — tank replacements in large homes running two units at once.
- PRV & Water Pressure — pressure problems in big houses with long runs and multiple bath groups.
- Shower Valves — worn builder-grade cartridges causing temperature swings and drips.
- Water Line Repair & Replacement — buried service lines on large lakeside lots that run a long way from the meter.
- Garbage Disposals — replacements and jams in kitchens that get heavy weekend use.
24/7 Emergency Plumbing in Cumming
A failure in a finished basement or a lake house that sits empty part of the week can run for a long time before anyone notices. That is why our emergency plumbing line is staffed 24/7 across Forsyth County. If you find water where it should not be, close the main shutoff, cut power to the affected area if it is safe to do so, and call (770) 966-9654.
Plumbing FAQs for Cumming, GA
Do you service lake homes in Cumming?
Yes. Properties around Lake Lanier are a regular part of our Cumming work, including older cottages that have been added onto over the years and larger newer homes on the slope. Sump pumps, hose bibbs, water lines running a long way from the meter, and heaters in unfinished lower levels are the usual jobs.
How often should a tankless water heater be flushed in Cumming?
Most manufacturers call for a flush once a year, and that holds here because the water carries enough mineral to scale a heat exchanger. Skipping it is the reason a unit that is only a few years old starts short-cycling, running cooler than it should, or throwing error codes. We do tankless flush service as a scheduled visit.
Why does my Cumming basement stay damp?
On a sloped lot near Lanier, groundwater pushes against the low side of the foundation and a sump pump is what keeps ahead of it. A pump that has sat dry through summer, a stuck float, a blocked discharge line, or a failed check valve all show up the same way. We test the whole assembly rather than just the pump.
Do you install water filtration in Cumming?
Yes. Homes on private wells in Forsyth County commonly deal with iron staining, sediment, hardness and odor, and treated county water still leaves scale over time. We install and service whole home filtration and conditioning, sized to what your water actually contains rather than to a generic package.
Why does it take so long to get hot water in my Cumming house?
In a large house it is usually distance. Water sitting in a long branch run has to be pushed out before hot water reaches the fixture, and the bigger the house the worse it gets. Undersized piping, a failing heater, or a recirculation setup that is no longer working can all make it worse. We trace it before recommending anything.
What causes low water pressure in a Cumming home?
The most common cause is a failing pressure reducing valve, which can drop pressure as it fails just as easily as it can let too much through. After that we look at a partially closed main, a leak in the buried service line, scaled fixtures and aerators, or a water heater full of sediment. Diagnosis comes before parts.
Who do I call for a burst pipe in Cumming at night?
Call us. We take emergency plumbing calls in Cumming and across Forsyth County around the clock, including nights, weekends and holidays. Before we arrive, close the main shutoff so the line stops feeding the leak, and cut power to any area where water is reaching outlets or fixtures if you can do it safely.
