Just Opened Up - Clogged Pipe??

[wetshoes1]

I actually went ahead & blew out all the lines with a stronger shop vac & everything is clear, except for the main drain.
I then took apart my DE filter, & cleaned it. The problem was it was extremely dirty so the water had no where to go.

It working fine now, except for the main drain. I can't see down there, the water is green. I am in the process of rigging up a setup to blow out the main drain.

Thanks, now I need to work on getting the water clear & clean.

it's interesting that I'm having this same problem ( clogged pipes)
perhaps I'll try the shop-vac method... thanks

I rigged a setup for the main drain, through the pump basket, and I can't get any air bubbles out of the main drain!

Are there any other ideas?

Hey wetshoes
I found out what was wrong with my system... turns out it was not a clog,
it was actually a very small air leak.
we had forgot to put the O-rings (rubber gaskets) in our attachments ( & possibly one of the hoses wasn't exactly threaded correctly)
anyway, this tiny airleak ( coupled with the water level not being overly high, but just at minimum required level), caused the system to not prime correctly

so I guess I'm saying, check all hoses and connections for possible leaks because it could really be that you are just drawing in some air
