Upon arrival, the technician excavated the area to locate the existing galvanized water line in the ground. The technician exposed a suitable section of galvanized piping and cleaned and prepped the pipe to properly install a new galvanized plug into the existing 90-degree fitting to seal off the abandoned line. Due to the age and condition of the galvanized piping, extra care was taken during the repair process to avoid compromising the existing line. Once the repair was completed, the technician tested the line and verified that the plugged section was holding properly with no visible leaks present at the time of service. The repair includes a 3-day warranty on the repaired section only. Warranty does not cover existing deteriorated galvanized piping, future failures, or replacement of the line if additional issues occur.

JIG Plumbing performed cable service on the drain line through the existing access point and completed a camera inspection. We were able to reach the stoppage and successfully clear the obstruction to restore flow. During the camera inspection, we were unable to fully determine the cause or overall condition of the line because excessive grease buildup coated the camera lens and limited visibility inside the pipe. We highly recommend performing a hydro jetting service to thoroughly remove grease buildup and any remaining obstructions within the main line. Once the line is properly cleaned, a follow-up camera inspection is recommended to accurately diagnose and evaluate the condition of the grease interceptor and drain system.

JIG Plumbing installed commercial graded kitchen handheld sprayer. Upon inspection of existing plumbing, technician recommends re-plumbing hot and cold water supply lines feeding the sprayer faucet to help prevent future leaks. Recommendation includes replacing both existing angle stop shutoff valves and installing properly hard-plumbed copper water lines with approved shutoff valves behind stainless steel utility sink. Existing plumbing components appear outdated and may be susceptible to future leakage. No additional repairs performed at this time unless otherwise approved by customer.

Upon arrival, the technician diagnosed the customer’s existing 30-gallon mobile home water heater and found the unit had failed due to a defective gas control valve and failed thermocouple. The technician also confirmed that the existing water heater model has been discontinued and replacement parts are no longer available, making repair not a viable option. The technician will remove and dispose of the existing water heater and replace it with a new Bradford White 30-gallon mobile home water heater. Installation will include bringing the system up to current code requirements. The technician will replace both the hot and cold water supply lines, replace the gas supply connection, and install a new sediment trap on the gas line for proper appliance protection and code compliance. To ensure proper combustion air and ventilation for the new mobile home water heater, the technician will also cut and install ventilation openings in both the upper and lower portions of the water heater cl

Upon arrival, the technician was shown an emergency shut off valve underneath the kitchen sink where the handle had broken off and the valve was actively leaking from the body of the valve. Prior to the technician’s arrival, the customer attempted to shut off the water to the home at the main shut off valve, but the existing gate valve would not fully shut down the water to the property. Due to the failed gate valve, the technician was required to shut the water off at the meter before repairs could be performed safely. The technician first replaced the failed gate valve located on the water service riser with a new quarter-turn ball valve to restore proper control of the home’s water supply and provide a more reliable main shut off valve moving forward. Once the new ball valve was installed and operational, the technician proceeded with the repairs underneath the kitchen sink. The customer requested replacement of all three emergency shut off valves underneath the kitchen sink, incl

JIG Plumbing preformed diagnostics to identify the cause of the leak. This process includes disassembling the valve, inspecting the condition of the cartridges, and flushing the valve in case debris is lodged inside. In some cases, flushing may resolve the issue; however, it is not guaranteed. This procedure is part of a process of elimination. Once the inspection is complete and findings are determined, we will provide the customer with appropriate repair options if needed. We will schedule a second visit with the customer to return and install the customer-supplied shower/tub valve.

The technician installed the customer-supplied pull-down kitchen faucet and secured all mounting hardware and water supply connections to ensure proper operation. After installation, the technician tested the faucet and inspected all connections to confirm there were no leaks. Since the new faucet did not utilize the separate side sprayer opening in the sink, the technician installed the customer-supplied sink hole cover to properly seal and finish the unused opening. The technician also installed the customer-supplied centerset bathroom faucet in the remodeled bathroom. As part of the installation, the technician assembled and installed the included push-button pop-up drain assembly, ensuring proper alignment and sealing of the drain components. After installation, the faucet and drain assembly were tested to verify proper water flow, functionality of the push-button pop-up mechanism, and to confirm there were no leaks at the time of service.

JIG Plumbing came out to inspect and diagnose customer plumbing concerns and provide estimate/s. Laundry valves are good cause of issue settlement build debris clogged filters on washer machine. Removed filter for hot and cold and cleaned washer is fully operational. Highly recommend replacing 1” PRV and installing water filtration system to protect home. **Important notes: 1.)The water pressure at the property is measuring **100 PSI**, which is higher than the recommended residential range of **50–80 PSI**. This indicates the **1” Pressure Reducing Valve (PRV)** is no longer regulating the pressure properly. High water pressure can cause damage to pipes, fixtures, appliances, and hoses, and may lead to leaks or premature plumbing failures. Replacing the PRV will regulate the pressure to a safe level and help protect the plumbing system from potential damage. 2.)Installing a Halo Zero water filtration system helps protect the plumbing system and appliances by reducing scale bu

Highly recommend this company, specially John. He came on Wednesday to do an inspection since our bathtub faucet wouldnt stop leaking. He inspected that and other things around the house we have been issues with and he told us what needed to be fixed and in what order. Turns out we needed to replace the shower valve and our water heater as well. John was very friendly, professional and polite. He explained everything in a manner that it was clear and concise. Gave us an estimate of the work, no pressure whatsoever. We ended up calling the company back later the same day since their prices were very reasonable. We also liked how professional the staff was. Thursday morning John came back right on time and began working on our shower valve and water heater. 5 hours later and everything looks great, no more leaking. We will for sure call them again for any other plumbing needs we may have.

I've used JIG Plumbing in the past and I keep calling them back for all my plumbing problems. Most recently I had Noah come out and help with a drain pipe that broke for our utility sink. Not only did Noah fix the broken pipe and get our sink working again, he also checked all the bathrooms and looked at a problem we had with our dishwasher not draining correctly. I think he fixed like four problems in this one visit, it was incredible. Noah took his time, was methodical, and we felt like he cared that we were looked after and that he didn't leave us with any potential problems he could quickly resolve for us. Just more reasons to keep coming back to JIG Plumbing.

Jig Plumbing was so responsive to my initial call. Jason came out to the house to survey my plumbing needs and provided me with a on the spot estimate and made some recommendations. No pressure sale at all! I had to wait to get the work done in the house and due to delay of the construction team that was workingon my house. JIG Plumbing Office adjusted the repair dates which was Outstanding! John T. of JIG came out did the survey of the repair and provided me with a revised estimate, executed the repair, left the space clean, and did an Outstanding Job! Thanks John. This Company originally provided and installed my Tankless Water Heater three years ago. One of the best decisions I ever made going with JIG Plumbing. You got to support your local companies!
