plumbing question

[cgomez87]

this is how i am thinking of setting up my drain and return any help on a better method if something is wrong with mine would greatly help thanks

The set up looks fine but my only constern is the sizes of your tubes. In the picture your drain looks about the same size as your feed line. Just wondering what the I.D. was?

+1 and your overflow drain needs no valve.

The only thing I see is that maybe have your union below the valve on lower return to spray bar? The valve on the drain would only be needed for a'Herbie' style with an emergency drain along side. Is this a Durso style? Also need to be careful with vinyl hose on bends as they have a tendency to kink.Cheers, Todd

Hope the one way valves never fail on you, or your tank is going to empty unto the floor. Not saying they will, but there always a chance.

Never ever rely on a check valve! They can and will fail and usually at the worst possible moment. If your sump is not large enough to contain every gallon of water above the check valve then eliminate that return. It will get you into trouble almost guaranteed.
