See if this is what you need. http://www.plumbingsupply.com/bulkhead.html Maybe thread the tank, and screw the fitting in the tank without using the backup nut, add a nipple and connect to your pipe with rubber hose to absorb vibration and prevent cracking.

Thanks, Paul. That helped, and I can picture it now.

Mahala, thanks for the link. We have considered something like that.

God bless,

John

I have a three inch one like that one that I never used.  I couldn't figure out a way to tighten the fitting.  My tanks are polyethylene.  I was going to cut a hole and then cover it with more polyethylene, but a local plastics welder said the plastic would eventually crack.

I got my fitting from Indelco Plastics and it was between $30 and $40.  A lot less money than plumbingsupply.com.

Darned BBS software erases a post on file size errors (192k )
I had the instructions and tools listed too!

Get one of these. ( your favorite plumbing supply house )

Cut in half ( not split )

Take clamps off.

Check to make sure the rib where the clamp was slips into the hole
and locks in place. Get your 3" PVC or ABS and cut a stub that you
will insert into the rubber sleeve once it is in the hole. ( use silicone )
on final assembly. Once the rubber is in, Shove the PVC or ABS into
the rubber fitting which expands it and seals the hole.

These are available to fit 2 through 6 inch pipes.

For a 3" use a 3.5 Inch hole saw. For a 2" use a 2.5 Inch hole saw.

This allows for a flexible joint which is not subject to breaking from
vibration or flexing. Oh.. Also since the stub is sticking down into the
top of the tank a bit, It gives you a little wiggle room to get things lined up later.
I have never had a fitting break or leak using this method.. It's almost too easy..
