Sticky pvc pipes connections - How do i connect disconnect pipes easily

[donzac]

Hi,

I'm having a LOT of trouble pushing the male end of a pvc pipe connection right the way into the female end of some drainage and spouting pipes. Then I'm finding it almost impossible to get the connections apart so I can glue them.

I've filed the pipe ends and cleaned them with a rag but it doesn't seem to make much difference. Is there something pros use to make the job easier, like talcum powder, grease etc.


Thanks for any tips
Cheers Don

Thanks, believe it or not my brother is a registered drainlayer and he doesn't use anything on his connections. he has a knack of getting them on and off without using any lubricants. The reason I never asked him was i was sure he'd say something dismissive and that i should leave the job to a real drainlayer.

Cheers Don

your brother needs to go back to drainlaying class. When laying drainage you need to cut pipe square, chamfer the end, clean it and then add pipe lubricant to help push pipes home. Pushing them on dry can force the rubber out causing the pipes to fail a test and snag toilet paper, those little white mice :;): and shite.

^^ what sean said
we use floplast gel on upvc and it works a treat with chamfered pipes

Maybe they do things differently down here in New Zealand. I went to two general building supply stores that sell pvc drainage
,and plumbing supplies, and neither of them had ever heard of pipe lubricant.

One of them said I had to go a specailist so I went to a
plumbing/drainage trade supply shop. They had never heard of a pvc pipe lubricant for "straight" plastic pipe(without rubber rings)

I find this baffling as I find it hard to believe that there isn't a demand for such a product. As even my brother, the drainlayer acknowledges it can be hard to push then connections right in and then to pull them apart again.

Tomorrow, I'm going to ring the company that produces the drainage pipe and see what they have to say.

I had a look on the internet about flopast but couldn't find any information about it. Do you wipe it off before gluing?

Are you installing push fit or a solvent weld system, a straight plastic coupling without sealing rings sounds like a solvent weld connection.

i thought this when every one jump on him, lol.

hes not using push fit system like we use hes using solvent weld system, and therefore do not lubricate with anything over than the adhesive, are you using pipe and connector manufactured by the same company as sometimes different manufactories tolerances cause a lot of swearing.

Hi,

I'm using a solvent weld system.

[flowjoe]

You don't use a lubricant then.

Square cuts, keep everything clean, apply glue/solvent, push together and work fast

or buy a push fit system..................much easier

Good question. I am using a mixture of two manufacturers products, as i got them off my brother at a cheap but expensive price, "Don't forget you owe me"

However, even when I join two products from the same manufacturer I still have problems but nothing that can't be solved
with a bit of exasperated tenacity

never mix manafacturers with pipe work
as giles says they got a lot of effs thrown into them trying to mix marley with osma or terrain
they have to be a fairly snug fit for solvent weld though,make sure its all correct before you start sniffi ... i mean using the glue
