Thoroughly satisfied with my Water Valve
Ordering from Supply House has proved to be quick and easy. My part arrived in less than 2 days. Just had to wait for the repairman. He also commented on the quick arrival of my order! Very satisfied!

I would buy again
Thanks for having this valve in stock. I was really happy to know that I could still buy this item. This water valve was easy to replace and I was hoping this was my problem for the hot water having cooled way down. Now have Hot water again. Got 18 years out of original !

Clean dishes again!
We are a church with an old dishwasher. It is very sturdy, but we needed to replace the water valve and were so happy to find it at SupplyHouse. When our first order was lost in transit, they very kindly overnighted a replacement. Super customer service.
