Most Liked Positive Review

Great product that was in stock. Shipped fast.

Installed on boiler system and working perfect. This company had it in stock when others did not. The price was reasonable. I will check here first before all the other stores. Thank you.

Most Liked Negative Review

Not holding 30psi

Opens between 28 -29 psi. Don't make the like they use to. Original 17 year old Watts relief valve Worked fine. Just changed due to age.
