OK I have drawn up a plan for a custom built sump. Here is what I am thinking:
Any one have any input as I am really just making this up as I go. Basically green is in from the cpr overflow 1 1/2 inch bulkead in overflow, so I thing it would be same for the piping?
Yellow is from the reeflo, whish is also 1 1/2 inch piping. I will be using some sort of a Valve to scale back the flow if required from the reeflo.
