Checked customer complaint about a leaking wash machine valve. The customer had a wash machine valve that was leaking when he turned it on and he needed it replaced. The customer kept the valve in the off position to keep it from leaking. Presented customer pricing to replace the wash machine valve with a new one. After pricing was approved I collected a half down deposit. The work will be performed once the required parts are acquired. CPI is not responsible for damage caused by the leak. Thank you for choosing CPI Plumbing and Heating.
Mounted new hose bib and in the crawl space cut a section of copper pipe out which allowed me to solder some pex adaptors on the copper and the pipe in the hose bib with 1/2â€ pex pipe. Slowly turned water back on and tested for leaks.
Arrived on site. Confirmed customer complaint of error code â€œ788-00 check dip switch settingâ€ and water not producing hot water. Customer also complained of power outage from night prior. Removed front cover and moved dip switch #1 from natural gas (off) to propane (on). Tested unit. Water heater performing as designed. Checked all other control settings at customers request. At this point I am not sure why setting was not in proper position. Proper position had been confirmed on original installation and had been running since March. Water heater is cycling and performing as it should. No charge for todayâ€™s visit. Thank you for choosing CPI Plumbing and Heating Inc.
Arrived onsite to customer complaint of a leaking 40 gallon natural gas water heater. Provided pricing for replacement of tank with either a 6 year warranty or a 10 year warranty, customer chose the 10 year warranty option, explained that he would need to drain and flush the water heater once per year to keep this warranty intact. Performed work, bled air from water heater while filling. Lit pilot, and checked for gas leaks and water leaks, none were present. Thank you for choosing CPI Plumbing and Heating Inc.
