Robert - Anacortes, WA

We enjoy having Jake in our home. He is efficient, personable and knowledgeable. Prices are on the high side, but we chose not to cut corners on infrastructure for our home.

Excellent work and communication.
Professional and Informative Estimate
Jon - Mount Vernon, WA
Brannigan and his apprentice were polite, informative and professional. Though their quote was close to another I had recently received, the way they explained the job and including possible roadblocks (and solutions) went a long way with me in deciding who to go with. So much, that I accepted the quote while they were here and paid the deposit. While the job has not started yet, I expect these two gentlemen will be professional and thorough.
Rebecca - Sedro-Woolley, WA
CPI was able to send Andy out sooner than anticipated. He was able to give us 2 different quotes and went to work as soon as we decided what we wanted done. We had a leak and he was committed to getting the job done, even though it took him well into the late evening. He finished the job and cleaned up ans put everything back where he found. We are so far very satisfied!
Customer complaint of clogged kitchen sink. Gave option for drain cleaning. Ran 100 machine down all the way as far as I could and was able to clear the blockage. Reinstalled p-trap and tested drain. Kitchen sink is now draining properly. Note: There is no warranty on drain cleaning. Thank you for choosing CPI plumbing and heating.
I pulled and reset the toilet in the basement with a new wax ring, bolts and supply line. I rebuilt the tub/shower valve with new factory Delta parts. I called Kohlerâ€™s technical support regarding the hall bathroom toilet. Kohler is sending out repair parts to our shop. I will contact you when the parts arrive.
Customer called in with a leaking pipe in a wall. Arrived on site and inspected the issue. There is a leaking 3/4â€ CPVC pipe inside the wall behind the customers hot water heater. The customer has already removed the sheet rock from this area and the piping is exposed. Provided pricing to make a repair on the leaking piping. The customer accepted the pricing. Shut water off to the home at the city meter. Cut out the leaking section of piping, installed a new section of pex piping, restored water to the home and bled air from the system. Brought the system up to operating pressure and observed the piping. No leaks are present and the system is working as designed. The homes water distribution system is comprised of CPVC type piping. This piping is very brittle and prone to failure. Pricing is being provided to repipe the home in PEX type piping. The homes main water shut off valve is also CPVC and has a broken handle. Pricing to replace this valve is also being provided.
High pitch sound in toilet Indicates possible high pressure, tested confirmed 97 psi, and later over 100 psi 80 psi is max safe pressure strongly recommend pressure reducing valve(s) to protect fixtures and piping. Partially closed valve on toilet to eliminate sound, this is not a permanent solution Performed flush and drain of both water heaters while filling house waterheater the drain down valve would not seal, replaced and enlarged drain down port, had to pump water due to debri in tank Refilled tank tested no leaks No warranty on any existing plumbing or plumbing fixtures Strongly recommend water treatment or filters to protect fixtures
Customer complaint of water leaking at outside hose bib. Gave option for outside hose bib replacement. Water was already turned off when I arrived. I informed David I would have to cut into the drywall to access the hose bib and CPI does not do drywall repair. Located hose bib after cutting into drywall. Removed existing hose bib. Installed new woodford frost freeze hose bib. Turned water back on to test for any leaks. No leaks at this time. Thank you for choosing CPI plumbing and heating.
