Our Happy Customers

Aaron showed up to fix a problem with our toilet. He was extremely courteous and explained CPI’s pricing and gave me an estimate, I felt the price was to high and decided to tackle it myself. Aaron called his supervisor to let them know that I had declined service and they told him not to charge me for the call-out since he was already on his way back to the shop from another job. The problem was fairly easy for me to handle this time but I do want to thank Aaron and CPI for their very fair treatment.Corky Culver

I can't say enough about how responsive CPI and Jose were in taking care of a pretty dire situation - a leak in our sewer line running up to the street. They understood we needed help right away, and Jose was there within 2 hours. We couldn't be happier with their service.

Your technician Steven Olsen was prompt ,courteous and very helpful in explaining the problem with my heater which is 20 years old and outdated. Bad heat exchanger . It was at that time we talked about all the options and decided to have a new heater and thermostat installed . Steven was very patient and thorough through the process of inspection and my new heater options. We are looking forward to the installation of the new heater .Well done .. Thank you , Bill Marsh

Brannigan and his crew did a great job replacing an old galvanized water main. While it initially seemed like a straight-forward repair, rocky soil complicated the trenching. Nonetheless, they worked extra to get it done. After that, the actual installation went smoothly and quickly. The trench was neatly backfilled and all extraneous material was cleaned up. A first class job. I highly recommend them.

Update:CPI has exceeded our expectations once again! I recently reviewed them after our first appointment when we were waiting for a part to arrive. Now that all the work is done, I wanted to leave an updated review.We recently bought a house and inherited a poorly-maintained boiler. It was a mess. The CPI team put in a ton of time and effort sorting through the various issues. They were transparent about the repairs and costs. They gave us a more than fair price on the work and were very focused on making sure we were satisfied with the result. I feel confident that they know their stuff and I can see that they really value their customers. Someone answered the phone every time I called and I always felt like a priority to them. Brenden and Steve went above and beyond to get our boiler back online. They have definitely earned a lifelong customer in us!Earlier review:CPI took our call over the weekend (most places didn't pick up or return our call) and was able to get us scheduled quickly. Brenden did a great job explaining everything and finding the problem. He worked very hard to find us the parts we needed and to fix the problem as quickly as he could. He did a high quality repair and showed great customer service in trying to find us a temporary fix while we waited for parts. We will definitely be choosing CPI for our future plumbing and heating needs.

I could not have asked or received better service from Victor and his team over at CPI plumbing. What I appreciated most was the honesty and professionalism. CPI was able to show me the exact problems with my piping, including photos and full explanations about why I was experiencing drainage problems. They didn’t cut any corners on the job, and it only took them a day to completely overhaul the piping in my 100 year old house. The cost was upfront and at no point did they try to upsell or shill other services. It was incredibly relieving working with them, knowing all of the problems they were going to fix, how they were going to fix them, and the cost of the project all up front. I will be calling them for service for years to come, and wouldn’t hesitate to recommend them to my friends and neighbors.

    Confirmed with customer that mainline was backing up into the building. Used cable down outside clean out multiple times retrieving roots. Mainline is now draining properly. Used camera through drain line verifying line is clear to city main. Recommend getting mainline replaced or root intrusion will cause the mainline to backup again. No warranty or guarantee on drain cleaning. Thank you for choosing CPI plumbing and heating.

    Had to take some parts from two different spouts that Tyler had purchased to make a watertight seal that didn’t leak back onto the wall this was an owner supplied tub spout install it was not part of the original Ruffin when I did the tub spout and shower valve months ago because I was given specific specs to do the Ruffin and the original tub spout would leak because it had a recall. Also adjusted the trim of the valve fixing the handle and putting the set screws and I recommend putting the glass door on or at least getting a shower curtain up before using it because water will get everywhere

    Checked customer complaint about a clogged toilet. The customer had a clogged toilet and needed to have it cleared. Presented customer pricing to attempt to clear the toilet with an auger. After pricing was approved I laid down a rug to protect the customer’s floor from damage. Performed augering of the toilet. After augering many times the toilet still flushed slowly. Presented customer pricing to pull and reset the toilet. After pricing was approved I pulled the toilet and discovered standing water in the pipes. I put the camera in the line and it was completely full of water. Presented customer pricing to attempt to clear the main line. After pricing was approved I used the camera to see how far the obstruction was. The camera went out to almost 150 feet and I did not find an obstruction. I used a blow bag to attempt to clear the main line with the high pressure water through an outside clean out. After using the blow bag for a while the line did not clear. I checked the man holes
