I added a 3/4″ check valve today. Just so happens that I was going to order one today online but Mike, a distributor (Premier Carwash Systems) in our area, pulled up at my car wash. So I just purchased the part from him…. really easy!
I hooked up my foam brush weep system today. The check valve at the far end is used as a plug because I did not have one with my today.
I just attached the foam brush weep to one of the pumps weep lines for now, but I will need to purchase some parts and mount it better later. The last picture shows the weep solenoid on the far left which is where I will be mounting the weep line.
