Job Locations and Reviews
Upon inspection, both bathroom lavatory sinks showed high temperatures, exceeding 100 degrees. The left bathroom had a reversed hot and cold supply line issue. After swapping the lines, neither supply stop functioned. We scheduled a visit after hours to replace the faulty hot and cold supply stops. Upon arrival, we confirmed the need for an after-hours visit. After turning off the water heater and replacing the hot side stop, we switched the supply lines on the faucet. The job was completed in about an hour.
Upon inspection, the A. O. Smith commercial water heater displayed an “Ignition Failure” error. Power cycling did not resolve the issue. A constant water flow from the condensate tube indicated a problem. After shutting off the gas supply, the combustion chamber was found filled with water due to an internal tank crack. The hot-side copper piping showed signs of electrolytic corrosion, necessitating replacement. The water heater was non-operational and required replacement.
Upon arrival, we found another technician and their assistant working on installing a new heater. We then focused on the mop sink faucet, which had a missing vacuum breaker, causing water to pour out. After locating the issue, we installed a new Zurn vacuum breaker. Post-installation, we tested the faucet to ensure the leak was resolved. Additionally, we identified that the chemical hose was not functioning correctly and addressed this issue as well. The job was completed successfully with the installation of the Zurn vacuum breaker.
Upon arrival, we documented the water heater with a photo of its rating plate. We then inspected the pressure-assist toilet in the right bathroom, identifying a broken handle that was causing it to constantly run and fail to pressurize. We removed the faulty handle and installed a new one. After installation, we tested the toilet multiple times to ensure it functioned correctly. The part used was a Flush Handle for pressure assist. The issue was resolved, and the toilet operated without any further problems.
Upon arrival, I took a picture of the water heater and its rating plate for documentation. I then inspected the bathroom lavatory sink on the right, which was experiencing slow drainage. I removed the trap assembly and thoroughly cleaned it to remove any obstructions. After reassembling the trap, I ran hot water for several minutes to ensure proper flow. The sink is now clear and draining effectively, resolving the issue.
Our team conducted a thorough gas line inspection to ensure all connections and fittings were secure and free from leaks. We meticulously examined the gas lines for any signs of wear, corrosion, or damage. Following the inspection, we proceeded with the fixture hook-up, ensuring all connections were made according to safety standards and manufacturer specifications. After the hook-up, we performed a series of tests to verify the integrity of the gas supply and the proper functioning of the connected fixtures. This included checking for gas leaks, ensuring the appliances were receiving adequate gas flow, and confirming that all safety mechanisms were operational. The job was completed with precision and care, ensuring the system was safe and efficient.

Upon arrival, I first consulted with the manager to understand the issue. The 1-inch PVC ice bin drain had a 1-inch 1/4 fern coupler that had failed, causing a leak. I carefully removed the faulty fern coupler and assessed the situation. To resolve the issue, I installed a new fitting and connected it with a hard pipe to the floor sink. This ensured a secure and leak-free connection. The drain is now functioning properly. I used 4 inches of 1-inch PVC and two 1-inch PVC couplers to complete the repair. The job was completed efficiently, and the leak has been successfully resolved.
Upon arrival, I assessed the rhino rinser and found that the top had blown off and was reattached. I turned off the water supply and carefully removed the entire valve. Each component was thoroughly cleaned to ensure optimal performance. After reassembling the valve, I reset the system and conducted a test run. Throughout the process, I maintained communication with Manager Melissa, who was present on site to oversee the repair. The system is now fully operational.
Upon arrival, I consulted with the manager, Nicole. I inspected the floor sinks and identified a clog in the front line sink. Using a small machine from the cold bar, I cleared the grease trap by running it back and forth. I then flushed the sinks with multiple buckets of water, ensuring water flow while working. The clog was successfully removed, and the drains are now functioning properly.
On 7/17/26, I was dispatched to address a reported issue with the left restroom. Upon arrival, I confirmed with the shift manager that the problem was indeed with the left restroom. However, an employee had already resolved the issue before my arrival. To ensure everything was functioning correctly, I tested both restrooms. Both toilets flushed and operated without any issues, confirming that both restrooms are now open and fully operational.
On 7/17/26, I addressed an issue reported by the store manager. Water was dripping from a large bundle of black insulated tubes in the main dining area, which led to the bar area above. This bundle supported the beer stand and taps, and the water was due to a significant temperature difference between the floors, causing condensation on the cold beer lines. The condensation was dripping onto the floor, which needed to be encapsulated to prevent further water damage. I carefully inspected the area, identified the source of the condensation, and implemented an encapsulation solution to effectively control and prevent future condensation issues.
On 7/17/26, I addressed an issue with the men's restroom toilet seat, which lacked bolts for proper attachment. I removed the broken seat and installed a commercial-grade open-end oblong toilet seat, ensuring a secure and functional replacement. The new seat was carefully fitted and tested for stability and comfort.
Upon arrival, I coordinated with the spa's front desk and proceeded to the physical therapy area to investigate a ceiling leak. I identified visible rust on the shower drain hanger and observed water dripping from the 1-inch PVC condensation drain directly above the affected ceiling spot. After running water in the shower for 20 minutes with no visible leaks, I discovered that the drain was sagging, causing water to accumulate and condense on the pipe, leading to the leak. I secured the drain to ensure proper drainage, which should prevent further condensation and dripping into the ceiling tile.
Upon arrival, I inspected the drain for the dipper well faucet, which was connected to a 3/4” CPVC line and a 3/8” supply line. The constant clogging issue was addressed by removing the supply line and adapter. I then installed CPVC piping all the way to the floor sink under the left freezer. The drain was secured, and I ensured the freezer was positioned correctly. The drain is now functioning properly. Parts used included three 3/4” 90-degree CPVC elbows, one 3/4” CPVC coupler, Flo guard CPVC glue, and two 3/4” 2-hole straps.
On July 2, Ashley, the kitchen manager, reported an issue with a grill that was not reaching the required temperature. This problem was unrelated to any previous work done by JMJ Plumbing in February. The issue stemmed from a recent installation by another company, which had added a 3/4" black iron tee on a capped line to supply two gas whips and regulators for two new pieces of equipment in mid to late June. Upon inspection, all equipment was functioning correctly except for the grill using 15,000 BTU. The gas pressure before the regulator was around 108 inches of water column (w.c.), while the minimum required for the device is 3 inches w.c. The problem was traced to the regulator's adjustment set screw, which was nearly turned off. Adjusting the screw restored the flames, indicating the issue was with the regulator. While it was not possible to test the gas pressure without disassembling the device, if the grill still did not cook correctly, we advised calling back for a regulator r
Upon arrival, I identified that the right bar sink's Marco was unplugged. I promptly plugged it in and allowed it to complete its cycle. After ensuring it was functioning correctly, I verified that the sink was operating as intended. I completed the task efficiently and signed for the job with Jetica, confirming the successful resolution of the issue.
Upon arrival, I assessed the reported low pressure issue with the Marco instant hot and other faucets. After thorough testing, I confirmed that the pressure was adequate at 50psi. I also inspected the bathrooms, finding the flush valves to be efficient at 1.6 gallons per flush. Despite the initial concerns, I found no faults with the Marco. If any issues had been present, I would have replaced it. The work was completed on the right bar sink, and I signed off for Emily.
Upon arrival, I assessed the broken Marco faucet and proceeded to replace it with a new two-handle instant hot and cold faucet. The new faucet was sourced from our shop, and I signed for Nichole during the pickup. I installed a 1-12” supply line, ensuring a secure connection. Additionally, I used a 3/8 x 1/4 compression fitting to connect the supply line to the faucet. To complete the installation, I utilized some 1/4” copper line from an ice maker kit, which was a cost-effective solution. The job was completed efficiently, ensuring the faucet functions properly.
On 5/27/26, I was called to address an issue with the filtration system. Upon arrival, I was informed that the handle for the filtration system outlet had been inadvertently turned off during cleaning. I promptly inspected the system and confirmed that the handle was indeed in the off position. I guided the manager through the process of locating and correcting the issue. After the handle was turned back on, I thoroughly inspected the entire filtration system to ensure all handles were in their correct positions. No further issues were found, and the system is now operating as intended.
Recently, we successfully completed a comprehensive water service replacement project. Our team began by thoroughly assessing the existing infrastructure to identify any potential issues. We then proceeded to replace the outdated water service line with a new, high-quality material, ensuring durability and efficiency. Throughout the process, we maintained a clean and organized worksite, minimizing disruption to the surrounding area. Our skilled technicians meticulously connected the new line to the main water supply, ensuring all connections were secure and leak-proof. Finally, we conducted a series of tests to confirm the system's functionality and reliability. The project was completed on time, and the client was highly satisfied with the results.
Upon arrival, I identified that the ice machine drain had detached from its glued position. I carefully reattached the drain to the machine using a high-quality adhesive, ensuring a secure bond. This repair restored proper drainage, preventing ice water from pooling. The machine is now functioning correctly, with water efficiently draining into the designated floor drain. The job was completed to satisfaction, and I confirmed the resolution with Alexis.
I successfully replaced the toilet seat in the ladies bathroom, specifically in the last stall. The task began with removing the old seat, which involved detaching it from the existing bolts and carefully lifting it off. I then inspected the condition of the bolts and the toilet base to ensure they were in good working order. After confirming everything was in order, I installed the new 1-open end toilet seat, making sure it was securely fastened with the appropriate bolts. I tested the seat to ensure it was stable and functioned correctly. The job concluded with a thorough cleaning of the area to leave it in pristine condition.
I successfully replaced the toilet seat in the ladies bathroom, specifically in the last stall. The task began with removing the old seat, which involved detaching it from the hinges and carefully setting it aside. I then inspected the existing mounting hardware to ensure it was in good condition. After confirming its integrity, I installed a new 1-open end toilet seat, making sure it was securely fastened to the bowl. The new seat was tested for proper alignment and stability. Finally, I ensured everything was clean and tidy, leaving the bathroom in excellent condition.
Upon inspection, the drain line for the ice bin was found to be improperly positioned, lying on the floor instead of draining into the floor sink. To rectify this, I extended the drain pipe to ensure it reaches the sink properly. Additionally, I incorporated a flexible section using a 1-1 1/4 inch Fernco coupling, which allows for movement and prevents breakage during cleaning. This modification ensures the drain line will function correctly and remain intact. The work was completed efficiently, and I signed for Eric to confirm the job's completion.
