JIG Plumbing will reposition the isolation valve on a Navien tankless water heater (approximately 4 years old) that has not previously been flushed. The existing valve will be adjusted (quarter turn to the left) due to obstruction from the gas supply line, which is currently blocking proper access to the hot-side service connection. Work will include removal and replacement of the isolation valve, with proper repositioning to allow clear access for future maintenance and flushing. A new T&P (temperature and pressure) relief valve will also be installed to ensure safe and code-compliant operation. Upon completion of the above work, the system will be flushed using a descaling solution. The descaling flush process will take approximately 30–45 minutes to remove mineral buildup and restore optimal performance.

JIG Plumbing responded to inspect a leak located underneath the bathroom sink. Upon evaluation, a burst angle stop was identified as the source of the leak. We recommend replacing both the hot and cold angle stop valves to ensure proper function and prevent future issues. Due to the property being a condo/apartment unit, the water supply is connected to a shared system involving multiple shutoff valves and a boiler system. In order to perform the repair, JIG Plumbing will need to locate and shut down the boiler system, as well as isolate the water supply. Please note: • Shutting off water to this unit will also affect multiple neighboring units. • A minimum 24-hour notice is typically required for water shutoffs in condo/apartment settings. • HOA coordination is required prior to scheduling repairs. ** Emergency Repair Authorization – Bathroom Sink Leak Customer has been advised to contact the HOA prior to shutting off the water supply.

JIG Plumbing will reset the existing toilet in the hall bathroom. We will clean the underside of the toilet and clean the flange. Provided the flange is in good condition, We will install a new wax ring and toilet bolts and check for leaks. We will also replace the fill valve at a special rate. The toilet reset went as planned. However, the right side flange bracket which holds the bolt is worn out and the notch has been widened. The technician had to hold the bolt in place while tightening to prevent the bolt from spinning and coming loose. Should the bolt come loose, a flange replacement is recommended.

JIG Plumbing will perform a sewer camera inspection through the accessible kitchen cleanout. We will provide a video inspection of the findings. The technician removed the cleanout cap and found kitchen grease buildup inside the cap (see photo). The technician inspected inside the cleanout and found additional grease buildup (see photo). The technician recorded a video (2 min 16 sec, see attached) and found crown buildup (grease buildup on the top of the pipe, see video). At approximately 8 feet 6 inches, the technician hit a partial stoppage that the camera was unable to pass (see video). It is recommended to return to hydrojet the kitchen/mainline to remove grease buildup from the sewage system. This will allow JIG Plumbing to determine the condition of the sewer line and determine the cause of reported frequent backups. Hydrojetting is the only legitimate way to remove grease buildup from the sewage pipes. A cable/snake will not remove grease buildup from the system. Additional

Water heater was leaking and I know it need to be replaced. Called JIG on 7/4 and customer rep was able to schedule someone to come the next day. Jason called later for additional info. John came the next day to inspect and offer quote. He was friendly but professional. He comes back Thea next business day with Raymond and work was down within 2 hours. I have additional questions on soft water and RO system as this was something our family could benefit. John offered quote and answered all my questions. Nerve once he made me feel uncomfortable about my basic (stupid) questions. He offered his opinions and I do not feel that hes pushing me for the service, which I appreciate. We will definitely use JIG service again.

Mr. Taylor Warburton should be the face on your company vans. He is not only diligent and honest, he is also efficient and skilled at his job. In the time that he spent testing and inspecting the drain, I found him to be very through. It shows that he takes pride in his work and likes his profession. He concluded that there was no leak, in the drain and that was the free estimate. I would also like to add that Daimon from JIG was also very courteous and reassuring, when I first made the appointment. I had informed him that even if there was a job, it would be a small one. But he said he would still send out a technician for a free estimate! It is so nice to have honest and hard working people in our community. You both are gems. I hope that JIG plumbing values, both of you, as their most comprehensive assets. I pray that God keeps you all safe and healthy. Thank you very much.
