Bestway Lay-Z-Spa Non Return A valve problem

Water builds up and has to come out somewhere...

[@johnb147pro]

Don’t bother, even with the lazy valve, water still finds its way through to the pump and leaks out the bottom of the egg (via the valve you pointed to inside the egg).

Should no water come through? When I open mine it gushes out.... lol

Would this cause E02 error? Thanks

E02 is blocked filter 👍
