 Re: wATER FLOW
On your return line just before it reenters the tank there is an elbow,in the downward side ot the elbow you need to drill a hole of about 1/8 inch.if the pumps go off for any reason the holes allow air to suck into the pipe and stop the siphon.That will make those back flow valves useless.Then your sump/fuge needs to be large enough to catch all the water in the tank above the notch's in the overflow.So basicly the sump/fuge should be about 1/3 empty to hold that water. |
