Pentair Bermuda Skimmer tied to Main Drain- how to blow out?

[blakeusa]

Helping a friend with his pool. All blown out and clear - except the main drain and one skimmer.

Skimmer in deep end has both openings plumbed - one to the pump/and the other appears to be tied to the main drain.

Shallow end skimmer is plumbed to pump and believe equalized to deep end skimmer.

How do I blow these out?

Tried blowing from the pump and skimmer at the same time and no bubbles from the main drain.

Plumbed like fig 1 I believe

Re: Pentair Bermuda Skimmer tied to Main Drain- how to blow

What are you using to blow them with? Most shop vacs or yard blowers won't develop enough pressure to blow a main drain.

If the skimmers are plumbed together you can blow until air is coming out the first skimmer and plug it while still blowing then blow until air is coming out the second one. You can then either blow the main drain through the second port in the bottom of the skimmer or make a connector to connect the two ports together and blow it through the skimmer line.

Thanks I think the problem is that even though I have a good blower Cyclone, it is a 9 foot deep pool and will use a compressor tomorrow and keep the PSI under 20. Thanks for the response. B

Thanks to this forum I assembled this simple plug and blew out my main drain with a compressor. Worked great...
