Glue for drainpipe

#181742

Postby PrincessB » November 20th, 2018, 5:20 pm

The downpipe at the back of the house has sunk into the ground leaving a gap, so the main guttering is spilling water.

It's not a big job, but one that needs doing when it stops raining.

I would ask whether it would be better to:

Glue the two bits together or,

Ram the downpipe back into the gutter bottom and glue one of the curclips that hold the downpipe in place.

The end result would be the same, I'm after the least messy option.

Regards,

B.

A self tapping screw usually does the job.

If you fix it at the top or at the brackets, further sinking will pull the gutter down or the bracket from the wall or break something.

You need to find out why the drain is sinking and fix it there.

Another possibility is a joint that can slide apart in the pipe itself,
e.g. https://www.screwfix.com/p/floplast-sp1 ... 10mm/47977
or if you have a similar joint at the bottom, lubricate its seals.

What type of downpipe is it PB?

Is it plastic, or one of the older, solid-metal pipes?

If it's plastic then we've had exactly the same issue a few years ago, and sometimes it's not initially evident that the insides may have become coated in a thick layer of sludge from the upstairs bathroom, and this adds tremendous weight to the relatively light downpipe.

The clips are designed to hold the weight of the plastic bit, and not the sludge, so over time they nudge down through the clips and eventually drop out the bottom of the hopper.

So I'd suggest a few things -

1. Take the pipe off completely and take a good look inside - if it's got a thick layer of sludge then clean all that off before you put it back up.

2. Sometimes it'll be clean, but there may be a blockage in the pipe or at the end where it goes into the drain, so check that too - water dropping from the hopper from height and onto any sort of blockage can also tap the pipe downwards over time, through the clips and out of the hopper holding.

3. Install an extra clip or two rather than using glue - much better in the long run, and you may well regret fixing the pipe using such a permanent method...

Cheers,

Duct tape. £5. Maybe called Waterproof fabric tape. Same problem as you. Downpipe dropped and separated spilling water everywhere. I used it for a quick 5 minute cowboy job when it was still raining. 5 years on its still working perfectly. And black tape on black gutter is unnoticeable.

LOL, I heard that during the Pacific war the Americans used duck tape to patch up the bullet holes in their P51s between missions. And those things have been timed at 437 mph. :lol:

Available in all sorts of colours. I especially like the transparent one with built-in webbing for added strength, although I rarely see it in Britain these days. In the longer term, however, the point about getting a saggy gutter needs to be taken seriously.

I am assuming that this is the usual plastic (pvc) stuff.

Seconded.

Ideally, use a stainless steel screw. Drill a small hole first (stainless is weaker than carbon steel).

If you want to stick it, you could use a solvent weld adhesive of the type used for waste pipes etc. such as this,

I have used double sided foam tape inside the downpipe brackets to stop the downpipe slipping down after being pushed back up.

Thanks for the excellent range of excellent and detailed replies.

Heads off to buy some black duct tape and stainess screws.

Cheers all,

B.
