Great service and communication

Trevor called us as well as our tenants when he was heading to the property. He was clear about what he was going to do before the repair and what he did to repair the toilet. He tested for leaks twice to make sure he fixed the problem. Trevor was professional and helpful. We have used CPI for rentals and our personal property with great success and recommend the company.

Hot Water Heater Install

Had a new hot water heater installed and once again Tony and his crew did excellent work. Very respectful of our home and our "dumb" questions. There were problems to the original install in which Tony was able to work on and made it right! Now we know it's up to code.

Confirmed with customer that toilet and shower in master bathroom was not draining. When flushing toilet water backs up into shower this is on the second floor. All other bathrooms are draining properly on the first floor. Provided estimate to attempt to clear mainline through toilet drain and customer agreed to work. Turned water off to toilet and removed toilet. Performed drain cleaning clearing out soft blockage about 8 feet out. Used camera through drain verifying mainline is now clear. Shower is now draining properly. Reinstalled toilet and turned water back on. Flushed toilet several times no leaks present and proper drainage. Thank you for choosing CPI plumbing and heating.

Arrived at customers home due to issues with water pressure on the hot side in the master bathroom and hot and cold water mixing. Performed vinegar flush on tankless water heater inspected cold water inlet filter, screen was clogged cleaned and reinstalled upon completion of flush Removed internal sediment with cleaning Upon completion of flush water pressure restored, water was still mixing, isolated faucet and hot water was working, replaced manifold tee. Tested water is heating properly, cold water sandwich when tub spout is turned on this is residual cooled water in hot water distribution being expelled then heated water is dispersed at fixtures. Remedy would be an external buffer tank (estimate to be sent from office) or tankless water heater with internal buffer tank Water pressure restored on hot side of water system Hot and cold water mixing resolved Strongly recommend full house filter between well and potable water system Tested water 5 grains per gallon see chart, softene

Arrived onsite to customer having a leaking hosebib that would let water into living room when turned on. Since customer was in process of selling house to prevent water damage, gave customer pricing for replacement with and without membership. Customer accepted with membership pricing. Began by cutting 8x8 hole in wall to gain access to hosebib. Turned water off to home and unplugged tankless unit. Provided and installed new Woodford Frost Free hosebib. CPI strongly recommends removing hoses in winter months to prevent freeze damage and to allow hosebib to drain. Performed KCM while onsite Customers water pressure is approximately 65PSI No active leaks visible in crawl space. Drained and flushed tankless unit for approximately 30 Minutes. After flushing ensured customer had hot water at all fixtures. Drainage piping in crawl space has no visible signs of leaks and appears to have proper grade on all visible piping. Ran water at all fixtures and looked for signs of leaks and

Performed a water leak repair on 1” copper water piping on 5/4/2022. Customer stated he noticed moisture on the pipes where the work had been done. Cleaned and inspected joints for signs of leaks. No leaks were identified. The moisture was determined to be condensation from the pipes sweating. Customer also requested a ball valve to be installed in the pipe between the inlet and outlet piping for the water treatment. Customer previously had a ball valve installed there, but requested I take it out yesterday. Presented pricing for plumbing diagnostic and informed customer that I would reinstall the shark bite ball valve. Customer accepted pricing. Shut off water to to the home and drained system. Cut out a small portion of copper pipe between the two tees and inserted the 1” ball valve. When the connections were secure, restored water to the home and inspected for leaks. No leaks were identified.

They turned the breaker back on and the control box with the capacitor was making a bad clicking sound. I pulled the panel open and using a multimeter i tested the capitol and it was not reading the ohms like it was suppose to. Double checked the incoming power and the pressure switch all checks out. I believe it is the control panel that need the capacitor replaced. Pump company Dahlman well and pump 360-757-6666

Checked customer complaint about bad angle stops. The customer had 3 multi turn angle stops that they wanted replaced with new angle stops. The customer also wanted pricing for a new main shut off valve. The customer lived in a town home so they would need to schedule a day to have he water shut off to their building. The customer also wanted pricing for a new bath tub in the guest bathroom. The estimate was sent to the customer before my departure. Presented customer pricing to replace the the angle stops. After pricing was approved I laid down a rug to protect the customer’s floor from damage. I turned off the water to the home at the main shut off valve. I removed the existing angle stops and performed the installation of the new shut off valves. After the new shut off valves were installed I performed a leak test with the customer. I turned he water on and tested the stops for leaks. The new angle stops performed as designed and there were no leaks when last checked. The customer

50 gallon electric water heater that services showers for the gym. Inspected the water heater and only saw small rust under the paint on the outer shell of the vessel, unit is located next to a mop sink. Water does appear to get splashed occasionally. Unit is still intact and is not leaking.

Task #1 - changed out the UV filter bulb, following the manufacturers instructions we swapped out the build and the lamp key. Task #2 - in the back pasture we changed out a 3/4” inch boiler drain, this valve supplies the horses with water Task #3 - opened the wall inside the house at the location of the outside hose bib. Used vacuum to remove all the water, unthreaded the hose bib. Secured a new piece of wood to the exterior wall, drilled a hole through it and installed new hose bib. The piece of wood aloud us to secure the hose bib to the wall

Arrived onsite to customer complaint of wanting her fireplace turned off, and to service the furnace. Furnace is from 2001, Average life expectancy is 10-15 years. Currently the furnace is 21 years old. Recommend replacement due to age. Unit is an 80% efficient unit with 3” venting, new 80% efficient furnaces require 4” venting, if customer would like to stick with 80% efficient equipment the venting would have to be replaced with 4”. If customer would like a higher efficiency unit, we would remove the 3” venting and replace it with a 2” pvc exhaust, and 2” pvc intake. We are able to reuse the existing hole for the intake and exhaust. However a condensate line would be required for the higher efficiency furnaces, we would be able to install a condensate pump and run the drain line out of the attic and into the gutter on the back side of the condominium or run a 3/4 pvc drain line out of the attic along side the gutter. This would have to be approved by the condo association

Arrived onsite to customers home to customer having not hot water on a This is an attempt to diagnose an issue with a natural gas water heater. Customer has stated that the pilot light has gone out multiple times in the past. Presented customer with diagnostic pricing for replacements as well as for diagnostic work on a 9 year old tank. Customer accepted diagnostic pricing. Took inlet gas pressure and measured 4.4” W.C. Checked mV signal on thermopile and received 419mV indicating the thermopile was operating properly. Checked for gas leaks and CO leaks while unit was under fire and found none to be present. Unit appears to be drafting properly. Cycled water heater multiple times in an attempt to recreate issue with pilot light not working. Pilot light and main burners were able to light multiple times without any errors. Customer had stated before that they had had issues with water being very hot and causing some people to be burned. Asked customer what they had the
