Best service and fast shipping!

We were having a hard time finding parts for our home water heater. Sometimes it's hard to trust a website you don't know about but don't fear nothing! This place is legit and fast shipping! Will definitely buy again.

Exactly what I needed and works.

I wish the picture and or documentation included that there was a feral/ bolt included for the small line (I believe that is the pilot light).

Great service.

Are stupidly ordered the wrong burner, a 16 inch when I needed a 14-in, and they immediately sent to 14 in. They had it in stock when even Honeywell would have had to wait 3 weeks.

Well Done, SupplyHouse!

After buying a thermocouple and having to return it, and after running to three stores in town, I discovered SupplyHouse.com. I wish I'd come here first. After learning that I couldn't just replace the thermocouple, I bought this burner assembly for less than 1/2 the price of other establishments. It arrived in two days! Installation was an easy 30 minute job. The instructions were very clear, understandable and in the King's English. (And yes, I do read instructions!) It was great to hear that familiar whoosh when the shower went on this morning. Thanks, SupplyHouse! Keep up the outstanding work!

Worked Perfectly

Part arrived in timely manner. Was essentially a direct bolt on job. The pilot gas line and compression fitting was separate in the packaging. And required a you tube video to figure out how to install properly. But easy enough to figure out. Installed on 30 gallon natural gas AO Smith
