More DIY Overflow Problems!!!

  • We are currently upgrading MFK. thanks! -neo
I replaced the valve and this time made sure the silicone was in there pretty good. It's still not sucking in as much as before. I sucked all the air out through the check valve and nothing.

So I'm assuming its the pipes, except it's been two weeks and its acting up NOW?

I mean, the PVC glue melts the PVC together, how can it get an air leak?

This really, REALLY sucks!

Are there any other possibilities?
