Performed diagnostic services to determine the source of the tankless water heater leak. The leak was traced to a failed heat exchanger, which is covered under the manufacturer’s warranty. Our technician coordinated with Rinnai technical support and successfully ordered the replacement heat exchanger to be shipped directly to our office. During the technical support call, it was also confirmed that the existing venting is designed for a condensing unit, while the installed model is a non-condensing unit. This venting configuration must be corrected to ensure proper operation and safety. To help prevent future issues, we recommend installing a scale prevention filter on the cold-water supply to the unit and performing an annual tankless flush to reduce scale buildup and extend the life of the heater.

Remove your toilet to access your main drain and attempt to clear it with an electric snake. Reset your toilet to ensure that it is leak free and operating properly. If unsuccessful due to improper access the charges will still be due and or credited towards any repairs. No warranty on improper access points. The technician removed the hall toilet and attempted to snake the line. However, the snake went the wrong direction and was coming up into the other toilet. The technician could hear the snake on the other side of the wall. The technician then removed the other toilet and snake the line. He was able to clear the blockage at the drop into the main sewer line. He then ran a camera 90 feet, where he could no longer push the camera. He found heavy scale and many wipes in the line. He reset the toilets with new wax rings and caulking and checked for leaks.

Upon arrival, the technician inspected the tankless water heater and discussed the system setup with the customer. Tyler explained that the home’s hot water is supplied by two systems — a traditional tank on the left side of the house and a tankless unit on the right side. The technician performed a visual inspection of the tankless water heater. No leaks or visible issues were found. The front access panel was removed for a closer inspection, and no leaks were detected. While testing water fixtures, the technician noted that the master shower had very poor pressure. Upon inspection, significant mineral and scale buildup was found at the restrictor in the handheld shower head. The technician removed the restrictor, cleaned the scale buildup, and restored flow — complimentary service. Further inspection revealed similar buildup at other aerators throughout the home. The hall tub was found to have no flow, which the technician believes is due to mineral and scale deposits that have lo

The 3/4 side has a 3/4 sweat MIP and quarter turn hose bib. The pipe penetrates the garage wall. The technician took the pressure and the pressure is currently at 90psi.

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!
