Job Locations and Reviews
Upon arrival, I assessed the dishwasher and identified an internal malfunction. The machine was not completing its cycle and was emitting unusual noises. After a thorough inspection, I determined that the issue was likely due to a faulty component within the dishwasher. I explained the situation to the customer, emphasizing the importance of professional servicing. I provided the customer with the contact information for the appliance company and advised them on the next steps for scheduling a service appointment. I ensured the customer understood the potential causes and reassured them that professional help would resolve the issue.
Upon arrival, I inspected the area under the Vertica machine. After shutting off the water supply to the machine, I turned the water back on. Immediately, water began spraying from the top of the valve box. I informed Manager Lacy about the issue and recommended that a work order be submitted for a Vertica technician to address and repair the problem.
Upon inspection, the floor sink drain under the three-compartment sink exhibited a soft clog, causing overflow when attempting to empty the sink. I employed an auger to dislodge the accumulated grime within the drain. Following this, I flushed the drain with hot water for several minutes to ensure thorough cleaning. After confirming the drain's functionality, I filled the three-compartment sink with water and successfully dumped it, verifying that the floor sink now drains properly.
Upon arrival, I inspected the drain for the three-compartment sink. The drain leads into a hub that directly empties into the grease interceptor. Due to the design of the hub for the three-compartment sink, a slight odor was expected. To address this, I treated the hub with Glug, a specialized drain cleaner, applying it twice. This effectively eliminated the smell. I then ran hot water through the drain for several minutes to ensure there were no lingering issues or odors. The treatment was successful, and the system is now functioning properly. Only half of a 20oz bottle of Glug was used for the job.
Upon arrival, we inspected the grease interceptor beneath the three-compartment sink. We found that the interceptor was draining slowly. After examining the outgoing baffle chamber, we discovered it was full of sludge. Using a small piece of 1/2” PEX, we broke up the sludge in the chamber. Once cleared, the interceptor began draining properly. We filled and emptied the sinks several times to ensure the issue was resolved. The grease trap is now draining as it should, with no further issues detected.
Upon arrival, I inspected the Water Ridge dual flush toilet, which had a small trickle when full. I carefully removed the old flush canister and installed a new one. After turning the water back on, I conducted thorough testing to ensure the toilet was functioning correctly. The new flush canister resolved the issue, and there were no signs of leaks. The toilet now operates smoothly, providing a reliable and quiet performance.
Upon arrival, we inspected the hand sink drain and faucet. The previous issue was resolved, but a new problem emerged. The faucet is leaking because the hot supply line was detached and incorrectly connected to a standalone AC unit. Only the cold water supply is reaching the faucet, causing water to leak from the hole where the hot supply line should be. Other faucets are also affected by this issue, making it impossible to shut off the water supply to prevent flooding until the AC unit is removed. We advised against using the hand sink until the AC unit is removed and secured the faucet with tape to prevent accidental use.
On September 4, I addressed two restroom issues. The first restroom had a malfunctioning sensor valve, which was replaced with a new manual flush valve. The second restroom had a "ThePint" manual flush valve that did not match the one installed in the first restroom. After consulting with the manager, both valves were replaced. I removed the existing Zurn manual flush valve from the second restroom and installed a new one, ensuring consistency across both restrooms. The work was completed efficiently, and I obtained the sign-off sheet and Ferguson receipt as documentation.
Upon arrival, I assessed the garbage disposal unit and identified signs of jamming and reduced functionality. To address this, I manually engaged the disposal unit, carefully turning it in both directions to break loose any obstructions. After several attempts, the unit began to rotate freely, indicating that the blockage had been successfully dislodged. I then tested the disposal by running cold water and gradually increasing the flow to ensure it was functioning properly. The disposal now operates smoothly, with no signs of strain or unusual noise. The job was completed efficiently, restoring full functionality to the disposal unit.
Upon arrival, I inspected the wall hydrant, which was found to be improperly closed, causing a leak. I used a church key to properly secure the on/off mechanism. After ensuring the hydrant was fully closed, I confirmed that the dripping had ceased. The hydrant is now securely closed and no longer leaking, ensuring the area is safe and dry.
Upon arrival, I inspected the hand sink drain. The plastic slip nut for the trap assembly was extremely loose. I removed the trap assembly, thoroughly cleaned it, and reinstalled it, ensuring all slip nuts were securely tightened. I ran water for several minutes to confirm the repair. The drain is now functioning properly with no leaks.
Upon arrival, I inspected the hand sink drain. The plastic slip nut for the trap assembly was extremely loose. I removed the trap assembly, thoroughly cleaned it, and reinstalled it, ensuring all slip nuts were securely tightened. I ran water for several minutes to confirm the repair. The drain is now functioning properly and no longer leaking.
I replaced the existing 1/2 inch hot and cold water supply lines with new ones, ensuring a reliable water flow for the fixtures. The process involved carefully removing the old piping and installing new sections to eliminate any potential leaks or inefficiencies. New shutoff valves were installed to provide easy access for future maintenance or repairs. The new piping was securely connected, and all connections were checked for leaks. The job was completed with attention to detail, ensuring the highest quality standards.
Upon arrival, I conducted a thorough inspection of the sink drains on the front line. All drains were found to be clear and functioning properly. To ensure optimal performance and eliminate any potential issues, I treated the three sinks with Thrift, a specialized cleaning agent. Following the application, I flushed each drain with multiple buckets of hot water to remove any residue and ensure complete clearance. As a result, the previously detected odor has been completely eradicated. The use of Thrift and hot water flushing has restored the drains to their proper condition, ensuring they remain free from any unpleasant smells.
On August 26, I arrived and identified a 1/2" supply line leaking from a corroded, abandoned compression stop. The stop was severely corroded and loose, allowing for easy removal by hand. After shutting off the water, I replaced the faulty stop with a 1/2" press ball valve. Once the water was restored, the leak was completely resolved, ensuring a secure and leak-free system.
Upon arrival, I identified that the hot water supply angle stop had been turned off, resulting in low pressure at the faucet. I promptly turned the stop back on, ensuring it was securely in the open position. Next, I adjusted the mixing valve to balance the water temperature and flow. After these adjustments, I tested the faucet to confirm that it was functioning correctly. The faucet now operates at the desired pressure and temperature. I completed the task efficiently and signed for the job with the initials "Izzy.
Upon inspection, I discovered a significant blockage in the common drain of the ADA stall, evidenced by feces and toilet paper backing up. To determine the source, I flushed the toilets in the adjacent stalls and the other stall in the same row, but these actions did not impact the common drain. However, flushing the ADA stall's toilet resulted in continued backup. I cleared the drain manually and then used a small drain machine to further investigate. The clog was located approximately 20 feet into the common drain, at the second turn. After addressing the clog, I tested all toilets in both rows to ensure the issue was fully resolved. Throughout the process, the manager was present to oversee the work.
I inspected and addressed issues with three bathrooms. The first required a new fill valve to stop the constant running, which was resolved by adjusting the fill level for a proper flush. The second bathroom's fill valve was adjusted to ensure a proper flush, which is now functioning correctly. The third bathroom's toilet needs replacement, and I provided a quote for a Kohler pressure assist toilet, including an open-end seat, extra-large bullhorn wax ring, 20” supply line, and haul-away charge for the old fixture. Additionally, I checked the water heater and T&P valve for leaks, inspected the sinks, and found a running toilet that was addressed. An invoice will be sent for the credit on the high water bill.
Upon receiving a request to address a cleaning concern for the nitro tap, I confirmed that it was not a plumbing issue. After discussing the matter with the shift supervisor, Rachel, it was decided that a specialized cleaning service was required. I coordinated with the company, icee, known for their expertise in nitro tap maintenance. They will be dispatched to perform the necessary cleaning, ensuring the equipment is properly maintained and functions optimally.
During the service, I addressed a broken strainer nut by replacing it with a plastic alternative featuring deeper threads, ensuring a secure fit. The bolts securing the chair were also replaced. This meticulous approach resolved the leak issue effectively. Materials used included one box of 1/4” screws and two small bags of butterfly nuts. The repair was successful, and the leak has been completely eliminated.
I replaced the drain hose for the shampoo chair. First, I sourced a new flexible rubber hose kit from a local hardware store. After removing the old hose, I installed the new kit, ensuring all connections were secure. I used a 1 1/4x1 1/2 simple drain kit and a 1 1/2 PVC tailpiece for the installation. Once completed, I ran water through the system to confirm the drain was functioning properly. The shampoo chair is now ready for use.
During the inspection, a persistent water leak was identified in the ceiling, specifically in the HVAC venting system leading to the roof. The leak was traced to a specific spot where water was dripping. To address this issue, it was determined that professional HVAC technicians are required to diagnose and repair the problem. I informed the store manager, who promptly arranged for the HVAC specialists to be dispatched as soon as possible. This area is directly above the door leading to the back of the establishment.
Upon inspection, the drain tray for the espresso machine at the bar had a rubber tube that was disconnected from the other drain parts. To prevent leakage, I reconnected the tube temporarily. The rubber tubing will need to be replaced by the specialized espresso machine technician. I ensured the temporary fix would not cause any leaks, and the store manager will contact the appropriate technician for the replacement. The job was signed off by Jay.

I successfully replaced the pressure reducing valve, ensuring the system operates within the optimal pressure range. I carefully removed the old valve, inspected the plumbing for any damage, and installed the new valve. I tested the system to confirm proper pressure levels and functionality. The job was completed efficiently, maintaining the integrity of the water supply system.

Plumbing in Roswell, GA: What We See Most
Roswell has the widest spread of home ages of any city we serve, and the first useful question on a Roswell call is almost always when the house was built. Within a couple of miles you can go from a nineteenth-century mill-era home near the historic district and Canton Street, to 1960s and 1970s ranches, to late-1980s and 1990s subdivisions, to brand new infill on a torn-down lot. Every one of those eras used different materials. Knowing the vintage tells us whether we are likely looking at cast iron, galvanized steel, copper, polybutylene or PVC before anyone opens a wall, and that shapes both the diagnosis and what a sensible repair looks like.
Water and terrain do the rest. Roswell sits on the Chattahoochee, with Vickery Creek cutting through it and a lot of steep, heavily wooded lots draining toward the river. In the lower neighborhoods near the water, basements and crawl spaces take on moisture when the ground stays saturated, which is why sump pumps and below-grade drainage come up more here than almost anywhere else in north Fulton. Steep lots also mean long sewer laterals with awkward cleanout access, and the mature hardwoods that make Roswell attractive are sitting directly over those runs.
The historic core adds a commercial layer. The Canton Street restaurant district packs food service into older buildings, which means grease lines, floor drains and original building plumbing all working against each other in a small footprint. Those kitchens need jetting and interceptor service on a schedule, not a call after the floor drain overflows during service.
Our Most-Requested Services in Roswell
- Sump Pumps — low-lying Roswell basements near the Chattahoochee stay wet after long rains.
- Repiping — late-1970s and 1980s Roswell homes may still have polybutylene supply.
- Sewer Camera Inspection — steep wooded lots make guessing at a lateral a very expensive habit.
- Sewer Line Repair & Replacement — old hardwoods over old laterals in the established neighborhoods.
- Water Heaters — basement and closet installs in older Roswell homes need careful venting and pan work.
- Shower Valves — 1960s and 1970s tub and shower valves are long past parts availability.
- Slab Leaks — the newer east Roswell subdivisions are slab-built and hide supply leaks.
- Faucet Repair & Replacement — mineral scale kills cartridges in historic-district kitchens and baths.
- Grease Trap Repair & Replacement — Canton Street kitchens run heavy volume through small older traps.
- Drain Cleaning & Clogs — scaled cast iron in mill-era homes slows everything above it.
24/7 Emergency Plumbing in Roswell
Older Roswell homes tend to give less warning before something fails, and a leak in a finished basement does its damage quietly. JMJ Plumbing runs 24/7 emergency plumbing across Roswell, from the historic district to the east side subdivisions, staffed by Georgia Master Plumber licensed technicians. Burst supply lines, sewer backups, failed water heaters, dead sump pumps during a storm and suspected gas leaks are all reasons to call (770) 966-9654 rather than wait for morning.
Plumbing FAQs for Roswell, GA
Does my Roswell basement need a sump pump?
If you are in one of the lower-lying neighborhoods near the Chattahoochee or Vickery Creek and your basement or crawl space gets damp after heavy rain, probably yes. Saturated Georgia clay holds water against a foundation for days. A properly sized pump with a sealed pit, a check valve and battery backup is what keeps a finished Roswell basement finished.
My Roswell home has polybutylene pipe. Is that a problem?
It is worth replacing. Polybutylene was used widely in homes built from the late 1970s into the mid 1990s, and it degrades from the inside where you cannot see it, then fails without much warning. If your Roswell home is from that window and has gray or blue plastic supply lines, a repipe removes the risk rather than managing it.
Do I need a permit for plumbing work in Roswell, GA?
For water heater replacement, repiping, gas lines and sewer or water service work, yes. Roswell is an incorporated city in Fulton County, so permits and inspections generally go through the city, and historic-district properties can carry extra review. We handle the permit under Georgia Master Plumber license MP210296 and coordinate the inspection for you.
What plumbing problems are common in Historic Roswell homes?
Cast iron drain stacks that have scaled down and cracked, galvanized supply that has narrowed to a trickle, clay sewer laterals full of oak roots, and decades of well-meaning renovations layered on top of each other. Access is the other issue: plaster walls, tight crawl spaces and finished basements make the repair path as important as the repair.
Can you camera my sewer line before I buy a house in Roswell?
Yes, and in Roswell we recommend it on anything built before the 1990s. The sewer lateral is not part of a standard home inspection, and it is the most expensive single thing that can go wrong. A camera run tells you the pipe material, whether roots are in it, and whether there are bellies, offsets or breaks along the run.
Do you service restaurants and businesses in Roswell?
Yes. We work the commercial side in Roswell, including the Canton Street and historic district food service corridor. That means grease trap service, repair and replacement, high pressure jetting of grease-loaded lines, floor drains and floor sinks, commercial water heaters, backflow testing and scheduled maintenance to keep a kitchen out of trouble.
Do you offer 24/7 emergency plumbing in Roswell?
Yes, every day of the year. Roswell calls that qualify as emergencies include burst or leaking supply lines, sewer backups, a water heater that has failed and is discharging, a sump pump that stopped during a storm, and any suspected gas leak. Shut off the main or the gas if you safely can, then call us.
