overflow issues

series3atomizer · 03/07/2012, 03:03 PM

why does the water keep moving up and down on the overflow. it seems it tries to drain then it moves right back up. is there a solution?

Sounds like you don't have enough air in your drain. Google "durso standpipe". A pic of your drain would really help.

+1 ^ It's creating a siphon, then sucks in water until siphon breaks and then builds up enough water until it starts the cycle again.

can this be fixed? it only happens on one overflow

Need to know how you have the standpipes/drain/overflow set up.

series3atomizer · 03/07/2012, 05:27 PM

drain pipe is on the right of the overflow. the return is on the left.
i am using flexible tubing to drain to sump. hopes this is what you wanted.

This is usually caused by inadequate air venting in the standpipe. Drill out the anti-siphon hole in the top of the standpipe that's having the surging problem. Do it in 1/16 increments until the flushing stops.

Does it look like this? Probably not, but this would fix it. In each one, and run a single return up over the back. Called a "herbie"

Do you have a hole in the top of your drain pipe? If so, is it clogged?

bnumair · 03/07/2012, 06:45 PM

a pic would help understand whats going on. but one thing is for sure that is siphon problem. either ur drain is not setup properly or hole above the drain maybe clogged etc. pic will help.

I am going to agree with everyone else and say it has to do with the sihpon. I would either drill one bigger hole or a couple smaller holes. I have a durso standpipe and it took 8 or 10 1/16" holes to get the water to airflow mixture right for mine to work properly. Good luck
