Use Teflon tape on friction-fit PVC?

[fuzzybabybunny]

I bought a hydroponics kit to mess around with and all the PVC pipes are friction fit into place. No threads any were. The kit came with a roll of Teflon tape.

Uhhh... My impression was that Teflon tape in only for metal threads. It should not be used on PVC threads, but I'm not sure about friction-fit PVC.

There's hardly any water pressure anywhere in the system (water just flows from section to section via gravity). Should I use the Teflon tape for these friction fittings?

it should work but there is that purple stuff.

and

I've used epoxy for a vacuum former for PVC pipe

Put it in your toolbox for later use. If it doesn't leak, you can't ask for more than that.

I've always glued that kind of PVC.

I've always glued that kind of PVC.

yeah, "friction fit" aka slip fittings, are meant to be glued together. I almost always use purple primer before gluing, but for low pressure, it's not always necessary. (but still recommended for a good bond)

Glue, fool.

FBB has got to be trolling...right?

Are they press fit? There are shark bite type fittings for PVC.

You can use teflon tape with plastic threads if you want, you usually don't need to though because it's not hard to tighten without it.

Are you growing pot?

That's probably the best PVC glue on the market. Primer is still recommended though.

In the world of pool pump/filter plumbing, it's common to use Teflon tape on threaded pvc connections.
Of course unions do not need any Teflon tape.

Of course unions do not need any Teflon tape.

That's because once you're in the union you don't do any work anyways.

Just experimenting with gardening. The thing on the right is what came with Teflon tape. So far there's been zero leakage that I can tell, even though water pools in each of the horizontal pipes.

You asked this on Friday, got answers, assembled the kit and you have two inch tall seedlings already? I'm impressed.

What you got growing there? herbs and beans?

Lots of random crap.

Basil, rosemary, spring onions, cilantro, Chinese chives, bok choy, kai lan, string beans, uhhhh... and a few others that I can't remember (they're Chinese).

I fucked up the cilantro. It's been warm here and they have started to flower, which means the leaves get thin and feathery and are not as nice to eat. The basil is growing really well though. Can't keep up.

Also making a self-watering bucket system for tall/thirsty plants with a trellis made from conduit and rebar. Peppers, eggplant, tomatoes, and other random stuff. If you do this don't use a toilet float valve unless you've got this hooked up to the water mains - gravity feed doesn't provide enough pressure to overcome the internal resistance of a toilet float valve.

The garden has Chinese veggies and a raspberry bush.

I also fucked up my two tomato plants in the last picture (I think) by planting them too close together (barely 2 feet apart, and they're indeterminates). Gonna dig them up and place them in buckets probably.

Instead of buckets use grow bags.

Similarly priced if not cheaper than buckets, and:

Very nice setup to keep them varmit/rabbits out. I had big problems with rabbits? & birds (I think?) eating my tomatoes. Looking to make some sort of drip feeder for my indoor garden, I always had a problems with over watering until I started using the smart pots. Can't say enough about them except for the soil dries out faster thus the need for a drip system in case I forget to look.

Ah missed your post yea those are great products I should've gotten the handle ones.
