Job Locations and Reviews
Repaired leaking pipes on a dishwasher supply line by cutting out a damaged 1/2” copper section. Installed new copper pipe, fittings, and a shut-off valve, then reconnected the supply line and tested to ensure a leak-free system.
Clogged drain repair: Cleared main sewer line blockage via 4" PVC clean out using 3/4" cable. Rodded to remove obstruction.
A/C tested in cooling mode. Remote reset from auto to cooling to prevent unintended heating calls; unit now producing cooling.
Replaced the relief valve. I believe that the bedroom system has a lack of circulation. I will explore circulator options for our customer.
Replaced the copper drain lines above the basement shower with new 3” pvc fittings. I also pulled the toilet to replace the flange above. I secured all connections. I flushed the toilet and checked for leaks. No leaks were found. We will return to do the rest of the quoted work once the clean-up company clears the crawlspace area of the sewage.
Performed precision maintenance on heating system. Is in good condition and operating properly at this time.
Technician secured pipes behind a wall that were loose and banging around according to the customer.
REPLACED 2 CARTRIDGES IN KITCHEN SINK BOTH WERE LEAKING WHEN WE ARRIVED
