Plumbing?

[oneknight]

Some time ago, the black drain pipe coming out of the slides broke.
I replaced it with PVC, and used green transition cement on the joints.

The other day, the PVC pipe came loose from the PVC connector.
I cleaned it up, reglued it with clear pvc glue, and gave it plenty of time to dry.

It let loose again the first time I ran the slide in and out.

I see that I need to work more on making it move easier, there is a lot of stress on this joint.
But why would the glue just let go?
Would epoxy be better?

Note we're kinda snowed in today and scheduled to leave in the RV tomorrow.

I did a quick Google search and found flexible PVC. The website is www.flexpvc.com.

Hi ! Welcome to IRV2! We're sure glad you joined the gang!

Sounds like some kind of flexible pipe would be called for here! Keep her between the ditches!

Good luck, happy trails, and God bless!

That is one of the drawbacks to having appliances & toilets in slides....But.... the modern day consumers insist on having them, so all the shack mfg's oblige... .

Thanks for the welcome and the tips.
I ended up regluing with PVC cement, and adding a wood brace behind that pipe to keep it from flexing so much when the slides moves.
I also neatened up the was of moving plumbing, wires, and hoses so it would move more freely.
There is a length of flex PVC, in a loop to the right of the picture.

I suspect your original joint failed because PVC primer and cement weren’t used. Were you able to get the transition cement cleaned off before priming and gluing? If not, you may still have problems. It might be best to start over with new pipe.

I was going to ask about the flexible pipe, but you just said it's to the right.

PVC glue is designed to 'melt' the pvc and bond them together that way. If you glued it once and it broke, the new glue isn't able to 'touch' the pvc to soften it. You might be better off starting over with new pipe.

Was there originally ABS pipe (the black stuff) there and you changed it out to PVC? ABS is usually better for drains.

Mine also broke. I could see where someone before me had repaired it. My son & I took it all out. As both of us are mechanics we designed a much better set up which has worked for over a year now.

By your picture it looks like the pipe that is unglued isn't sitting flush with the back wall. That's what was wrong with ours the angles weren't correct & putting to much stress on it. That's why we cut it all out & redid it & also supported it better.

It was originally all black pipe. It originally broke 2 years ago, actually snapped the pipe while the slide was going out!

We were fulltimers then, and PVC was what I could get. I cut the shattered pipe square, added the coupler and replaced the rest.
Then forgot about it.
Figures it let's go 2 days before we leave for the Tampa show.

Hopefully it holds together. Slide needs to go out and in 5 times...

In the spring I'll fix it right.

Ive been on that journey and more than once...and frustrating indeed.

I use many sealers with no real success for any length of time

There are many ways to do this and here is my very simple fix that has lasted 4 years.

Simple re-glue it put it back together then drill a very small hole maybe 1/16 thu the side of the coupler and the pvc tube then take a very short machine maybe 1/2 deep ( just deep enough to go thu the coupler and pvc pipe) and a use screw that fits the hole, then spiz the screw a bit with your sealer and screw it in ...job done.

I know I will get trashed for this but I cleaned up the connector first with acetone or MEK then this what I used to seal it.

Very easy and works ( at least for 4 years no)

Happy Trails

If it fails again, use the 2 part epoxy. That should hold it till you can get to it the spring.

A pics worth a thousand words

Drill hole at arrow tip and use a small stainless machine screw just long enough to go thu both pieces of the connection so they cannot pull apart.

Hope this explains it better

again 4 years no more headaches

After we stopped for the night, turned on the kitchen sink and the water went on the floor... [emoji32]

That fitting had been reglued so many times...

So I pulled the couch out, opened up the cabinet, cut out all the old pipe, went to Lowe's, and fixed it right.

I had the same problem in my 2015 signature. I used a rubber union which you can buy at any plumbing store. This will take the stress off the pipe. Did this over 5 years ago with no problem since.
good luck, jAKE
