"This was by far the absolute worst experience that I have ever had with any company. The plumber came out for a shower that was not draining. I am on septic and let them know that my septic was just pumped in July. However they wanted to check anyways. After checking under the baffle inspection, I was advised by the plumber that my septic tanks were full and needed to be pumped. I contacted a septic company they came out first thing the next morning and checked my septic tanks, they were not full and ironically enough was able to pull out a huge clog of toilet paper from the baffle. He advised this is something that the plumbers do but since we just had one out the day before and they did told us the wrong information he would happily fix the problem for us. My husband called Riley Cahill (the manger) the next day to try to talk to him about the situation and try to find out why we were charged so much since there was not an itemized receipt. Riley proceeded to get very defense and angry and HUNG UP on my husband. He then called back left a message that saying he will check with his plumbers on Monday and get back to us. Monday morning I called Riley Cahill to have a conversation of what went wrong and how we will remedy the situation. He proceeded to once again get very upset, raise his voice and was insanely disrespectful (telling me to be quiet and stop talking). Then hung up on me as well. After that he called back to tell me I was wrong, and hung up on me again. I told him during the conversation that I was going to warn anyone I could not to use this company through reviews, DO NOT USE THIS COMPANY!!!!"

"I requested an HVAC service call quote from G&S Heating through Angi, and received a "deal" via Angi for $129. I chose them partly due to that price. G&S Heating ended up billing me $280, and said that was an old outdated deal and would not honor it. Irresponsible and incredibly poor customer relations. Also, the technician they sent did not seem very knowledgeable or experienced. He said the thermostat reading issue I was having would require another service call and the possible replacement of an expensive circuit board. I ended up fixing the problem myself. I will not be using G&S Heating again."

FAQs for water heater repair or service projects in Black Diamond, WA

Warning signs include fluctuating water temperatures, a pilot light that repeatedly goes out, unusual noises from the tank, or complete heating failure. You might also detect a rotten egg smell, indicating a potential gas leak, or notice water that never reaches the proper temperature. If your water heater is over eight years old and displaying these symptoms, the gas valve is a likely culprit. Professional inspection is recommended, especially if gas odors are present.

Water heater gas valves are not universally interchangeable. Each valve must match your specific water heater's make, model, and specifications. Important compatibility factors include gas type (natural gas vs. propane), BTU rating, connection types, and physical dimensions. Using an incorrect valve can result in poor performance, premature failure, or dangerous gas leaks. Always consult your water heater's documentation or a professional plumber to identify the appropriate replacement valve for your unit.
