    Great tech, but nickle dime price

    Review of CPI Plumbing & Heating

    Josh was our plumber and he was awesome. Nice, very task orientated (he didnt take breaks, lunch or bathroom calls), and did an excellent job with the sink install. We upgraded our sink from a Glacier Bay 2 bowl sink that was really crappy to a Kohler stainless steel farm sink that we had bought 2 months ago. With going from 2 drains and dishwasher vent to a single drain, reinstalling the garbage disposal and drilling and reinstalling the original dishwasher air vent, Josh busted his butt! He ended up having to widen the hole for the drop in sink and worked relentlessly on drilling the proper diameter hole for the vent and getting it fitted properly and hooked up. When we tested the dishwasher it was even more quiet (its a Bosch and is super quiet) and somehow he fixed the door to it from when my mom had fallen on it couple years ago (She has Parkinsons) and it even closes normally and is straight again. Joshs inspection of the task was detailed and had created a detailed invoice and estimate. He upgraded our shutoff valves under the sink from 30+ yr old plastic knobs to metal. The only thing we didnt like was how the company nickle-dimes you to death for the job. they charged for the removal and install of the sink (which we knew), installation of the faucet ($200 and some change) etc. The only thing that he pitched at us, as from reading other reviews this seems to be a common problem, was replacing the plastic knobs and the company membership. With out the membership price the job was going to be $2,000 and change but with membership it was $1,800 and some change. We were surprised by the pricing but with living on an island with very limited services (one place we had called returned our call once then we never heard from them again, even with calling and leaving messages), one of the few companies an hr away that comes out to where we live. With health issues with my mom, dad and myself we went with CPI. And as the task progressed and new problems popped up, there was no way we could have done it due to lack of parts, tools, knowledge, and health problems. Josh's work was outstanding and he had everything up and running and tested in 6 hrs or so (drilling and widening the opening took the longest).

    Checked customer complaint about a leaking water heater. Customer had a 30 year old electric 50 gallon water heater that began to leak. Presented customer pricing to replace the existing water heater with a new 80 gallon HTP electric water heater. After pricing was approved I performed the water heater replacement. I drained and removed the existing water heater and cleaned the installation area. Performed new water heater installation. The new water heater was installed with new foam pad, earthquake straps and water supply lines. After the water heater was installed I filled and bled the air from the water lines. Performed leak test with the customer. There were no leaks when last checked and the water heater performed as designed. The water heater was set to 120 degrees. I went over the warranty information with the customer. Customer understood that they only have a certain amount of time to register their water heater. Customer was happy with their new water heater. Manufacturer r
