Do-it-yourself check valve for a Champion GTP80 motor pump/Drilling water wells
I will show you how you can make a durable and reliable check valve for a motor pump with your own hands. Friends, by mistake I glued the check valve to the front cover of the hydraulic part on the wrong side, it is necessary that the round insert (from another valve that I added) looks at the snail, i.e. inward. THIS IS IMPORTANT!!!
