AWESOME!

CPI needs to be very proud of the level of some of their new and younger employees, of which we have had the need for their expertise and service. They are very thorough and exceptionally polite and courteous. This again pertains to Aaron for our plumbing service call. We can't say enough about his professional level of service, as well as a very personal employee. Just excellent! 10 STARS!!!!

Great Service

CPI came out and and gave me a quote to replaced my furnace. They came in within a week and replaced the furnace in a timely manner. Davis and his partner were fast and efficient and cleaned up their area. I am very pleased with my new furnace and how everything was explained to me.

Arrived onsite to customer request to install caulking in a couple missing places. Customer also noticed then when tub spout was running shower head would also come on. After a long diagnostic process found that base pex 90 was the issue and was restricting flow enough to pressure up Shower line. Replaced and supported new fittings and tested new installation. No leaks present. Thanked customer for her patience and for bringing the issue to our attention. Tub and shower is now properly functioning. No charge as work was under warranty

Without membership Note: Grinder discharge piping required to be cleared of sewage by others, prior to replacement Note: This is an attempt only to correct the hammer issue. There is no guarantee and further diagnostics maybe required to identify the source of the issue.

Could not find the leak under the slab. We first went into the programming of the water softener call tech-support and we walk through unlocking the head then going over the usage over the last few days and since Friday usage has gone up to 1000 gallons a day this is why the softener would re-GEN three out of the last four days it is excessive usage and would need to clean itself we tried to find the leak underneath the two wings of the house that have crawlspaces but could not locate it. American leak detection is coming out the following week to try and locate where the water is leaking at because I believe it is under a slab.

Arrived onsite to perform the KCM on the furnace. Began by giving the unit a call for heat. The unit kicked right on. Tested my inlet gas pressure which gave me a reading of 7.47 W.C. Flame sensor was pulling 1.1 micro amps. Blower was pulling around 4.53A. Inducer was pulling 0.53A. Measured for my Delta T and got an air temperature differential of 30 degrees. Tested for carbon monoxide inside the home and found 0PPM. Tested for gas leaks on the furnace and water heater gas piping and found no traces of gas. Tested operation of thermostat. Thermostat was functioning properly. All measurements recorded today were within manufacturers specifications. Thank you for choosing CPI Plumbing and Heating!

Arrived at customer’s home due to issues with lukewarm water. After discussing the problem with the customer, temperature of the water was taken and it was found to be 78°. Customer agreed to proceed with an electric water heater diagnostic to figure out the cause of the problem. Proper diagnostic procedure was followed and the upper and lower thermostat and elements were tested. Both elements were found to be no longer working and both thermostats weren’t working as designed. After discussing the findings with the customer, several options were given to fix the problem. Customer agreed to have the upper and lower thermostats and elements changed out. Power and water was shut off to the water heater and the tank was completely drained. Upon removal of the elements they were found to be completely corroded. New elements were installed and the thermostats were replaced. The water heater was filled back up completely and power restored. The elements and thermostats were then tested a
