Just out of curiosity, where is your return pump sucking the water from? The center chamber with the PVC going down or the last chamber?
The last chamber. The pipe from the T in the return pipe is just to ajust the flow from the Mag Drive. I don't know if I am going to need it but thought it might be good to put in just in case. I'll just let the over pressure flow back into the sump so as not to over heat the pump by restrickting it with a ball valve.
