Product is great, but service at SupplyHouse is better yet
I mistakenly ordered the wrong size. SupplyHouse sent me the correct size (1 1/4") along with some other parts I needed. Everything arrived quickly and was exactly what I needed. Patrick, at SupplyHouse, imediately issued an RMA for the original part. I will be coming back to SupplyHouse for future orders!

Similar reliability to another post
This valve lasted just about 2 years. The cycling has become about every 15 min so now I'll have to replace it... again.

Lasted 2 years to the day
Bought this for the Watts name and hoped for added durability over cheaper checks after I could not get the brand I wanted. Began leaking down and causing pump cycling after 2 years. Previous check valve lasted 15 years. (Simmons) I'll go back to and stock the Simmons brand from now on.

Another well made Watts product
Well made - good casting and precise clean machining. Easy to find technical data available for those of you interested.

Solid Construction
I replaced a failed well pump check valve in the pumphouse with this Watts check valve. Flow rate is 21 GPM through this 1" spring check valve. Watts pressure drop curves show 1 psi pressure drop at this flow rate. Crack-open pressure is low. No backflow of water when pump is off.
