reuse rubber PVC coupling?


Just a simple question. Can you reuse a PVC rubber coupling if you open it up? The convenient place for me to snake out a drain would be at a rubber coupling, but before I open it up, I want to know if I need to buy a new one first.

Talking about the ones with hose clamps on each end? If so there sold at Lowes, HD, any hardware store, plumbing supply.
Show us a picture of what your trying to do and I'd bet we can tell you a better way to do this next time.

Here is the image.



A proper cleanout sounds quite a bit more work than just disconnect this quickly. How many times will I need that in my life?

Actually not too many more before the threads rot out on the galvanized and you have a leaker.



Change that baby out.

Well #1 one all that old steel plumbing needs to go. If it's not leaking now it will. It rust up from the inside and will get smaller and rougher as it gets older.
#2 that's the wrong type of tee in that line and cause the line to plug up.
a clean out could be added by simply cutting that PVC and adding a clean out Tee.
As far as how often your going to have to clean it out, you tell us. Your having to do it now, right.

reuse rubber PVC coupling?


Guys, I appreciate all the advice. Tell me more. We recently bought this 55 year old house and there is a lot to do.

Here is my pipe setup coming from the bathroom:



(Don't tell me about the amateur wiring - I know - it will be fixed.)

The PVC pipe is the bathtub drain. The vertical one is (probably) the sink. And the big one is (I think) the toilet. It's hard to see, but there is a vertical pipe in the far corner, and if I'm not mistaken, that's the vent.

The steel pipes eventually go into clay pipes in the ground. I know this because we recently dug up the sewer in the backyard to install a backflow preventer valve. But where the steel pipe exits the basement, it's under a porch outside, so I can't really dig it up to replace that steel pipe. OK, I understand that the T is the wrong type. What type should I change it to? All in all, what do you recommend?

All the help is very much appreciated.

The tee in front of the rubber coupler needs to go...
replace it with a sanitary tee. <--Need to do
immediately behind it put in a 45 tee with the clean-out cap. <-- Need to do
then the rest of that section down to the stack <-- May as well do
and the vertical riser section up to wherever it goes. <--Won't hurt to do

Letís take this one step at a time, what is clogged? If itís a tub or shower you can just usually on a tub go through the over flow and in a shower remove the grid and snake through that, providing that you have enough cable to get to your clog. Best to cable with water in the line so when you break the clog the standing water will help flush it way, run plenty of water after clog breaks and while you finish Roding the line. By the way the suggestions made by some of these guys are something to keep in mind that plumbing needs to be taken care of.

Both the tub and the sink are slow. Neither is completely stopped. The toilet is fine. So it's pretty clear where clog must be.

Look at the OP's earlier post with photo - that tee looks like it's already a sanitary tee. That's wrong; needs to be a wye.

Those lines need to be 2" and vented if there not.

Indeed, it's sanitary. So do I really need to replace it with a wye?

The vertical from the sink is 1 1/2 inch, same is the PVC from the bathtub, but after the tee, it's a 2 inch pipe. As for the vents: I can see that the tub is vented, and there seems to be a vertical vent on the main stack. That's what I see, but I assume they all vented correctly.

In the pic I first thought you had nothing there at all...
that the drain was t-boning the lateral.

The prescription is that you need more oomph! when that stuff comes down the pipe
see what will fit (a wye on the line and a 45?)
