New Holding Tank Fittings?

[rwidman]

I don't know why you'd consider a standpipe to be easier than a diptube. With a diptube, you have a piece of PVC pipe and one 90 degree hose fitting on the top of the tank. With a standpipe--as your illustration clearly shows--you need a tank fitting, a short piece of hose, a coupling, a 90, a piece of pvc and another 90 plus anaother coupler to attach a hose.

But it's your boat, bigfish...do whatever floats it for you.

A standpipe is not easier than a diptube for a new installation and I didn't think I implied that.

It would be to retrofit an existing tank with the outlet(s) at the bottom without having to cap them off and cut a hole for a diptube.

In some installations, there would not be clearance for a diptube. We have to work with what we have.
