Plumbing problem

[GOSKN5]

I am running an Eshopps Eclipse overflow on my 180... it has 3 drains.. one is emergency... other two durso style

It has been running fine for over a month now... I have turned off the return, etc many times.

Typically on restart the emergency will drain for a couple of seconds until the syphon starts on the other two drains...

Today I turned off the return pump to do some cleaning in the tank and the other two drains will not start for some reason.. the emergency is doing all the draining.. even if I turn the return pump down significantly the others dont start..

Any ideas on what happened? Or a solution?

Do you have 180 elbows on your durso pipes? if so, do you have holes drilled in them?

 

[GOSKN5]

Yes 180 on both other drains.. no holes drilled.. should I drill on top of both?

Yes. you probably have airlock. Drill a small hole on the top of the 180 and you will likely solve your issue.

Thanks! That fixed it, I knew this was an option, but since it has been running fine for months I was confused as to why it would happen all of a sudden

Airlock doesn't always occur, but when it does, it completely blocks water flow. the small hole aĺows air to escape preventing airlock, yet reducing sound tremendously.

Glad you got it working again.
