How to connect vinyl tubing to pvc

Jake_the_reefer · Jul 18, 2020

so i have a used overflow that has a chunk if pvc still glued into the bulkhead and i want to go the route of vinyl tubing for plumbing.
What kind of part do I use to connect the vinyl to the pvc? I want 1 inch vinyl and the current pvc is also 1 inch.

You would need to use a hose barb to go from pipe to hose.

Your friend has shared a link to a Home Depot product they think you would be interested in seeing.

What I do is use tubing that is nearly impossible to put over the pvc when at room temp. Boil some water and submerge the end of the tubing until it is very pliable. WEARING GLOVES (it'll be very hot!) then force the tubing onto the pvc. If you can then rapidly cool it (icewater), great. If not, allow it to cool. As it does, it will shrink fit itself to the PVC. If done correctly, you'll have to cut the tubing to get of off the pvc. If you are really nervous, use a plastic or stainless hose clamp. I don't bother with that and have yet to have one leak. I've done it that way for over 30 years without issue.

The big box stores sell an adapter that has a socket for pvc pipe on one side and barb fitting on the other for the hose.

You can see it right above the red valve handle where it transitions to black vinyl.

You want a barb fitting for tubing.

Many fittings on BRS, just search "barb" if you want it to involve tubing.

Would it be better to just replace the bulkhead entireley (because it has pvc glued in it) and use something like this?

That piece could attach directly in a bulk head if you buy a new bulkhead if that's what you mean. The bulkhead is what makes a watertight transition from the tank or other container to the plumbing.

Yeah I would be replacing the bulkhead because this one has pvc glued in it. It wouldn't hurt to just invest in a new bulkhead and get this barbed adaptor.

Sounds like a good idea, it looks like that is a slip adapter and would need to be glued to the bulk head. Sorry if you know any of this but it seems like you could use plumbing help so please just disregard what you already know. Make sure the bulkhead and barb have comparable ends either slip to slip or normal pipe thread to normal pipe thread. If you go with glued slip fittings please make sure you use an appropriate (transition) cement for the materials. The black ones you posted look like they may be abs.

I appriciate the tips. I was actually going to ask about glue next.
