Excellent pump!
By Verified Buyer on 10/14/2015
I bought this for a DHW recirculating application. The high flow of this pump allows minimizing delay of hot water to faucets when triggered by turning on a light in the respective bathroom one is using via a smart home hub and outlet.

where is the check valve located?

Check valve is a little white plastic part inside the volute opening, right at the flange. If you look at the product picture, you will be able to see it.
