Perfection!

This part was exactly what I needed and had absolutely no problem installing it. I ordered the parts on a Wednesday and received them on Friday! Very pleased with my purchase! My hot water heater is back up and running smoothly! Thank you!

Would only buy from this place from now on

I needed the water control valve for our heater ASAP. No one could get one to me for a couple weeks. Having wife and 3 kids I needed it ASAP, so I called supply house, ordered it and had it here the next day! They were also cheaper than everyone else!!

Direct Replacement

Direct replacement for the valve on my water heater that froze and cracked in our last winter power outage. Took about 20 minutes to change out and get back going again.

I would buy this again --- factory oring was bad

I installed this and everything is working! Factory o-ring was hair lipped for 11 years then started leaking and so Control valve had all new seals with it. so just popped it in and back in service.

Water control valve

No water was coming out hot side. No error codes on the display either. I replaced the water control valve and water is now flowing out of the hot side and water heater is working perfect.

I would buy from SupplyHouse.com again

Product delivery was right on time. I needed to replace the flow control valve urgently as we were without the hot water and SupplyHouse had promised the free delivery within 2 days. It came on time and I am quite thankful for it.
