Grey Waste Pipe

Hi

Today my grey waste pipe with the emptying tap on it became detached from the pipe leading to the holding tank.

I managed to get under an re insert it into the elbow bend it came out of but the pipe still rotates when I try and turn the tap.

What can or should be used to firmly attach the small diameter pipe into the larger one to stop the rotation.

I did think of using insulation tape in a figure 8 around both pipes but I would think over time and weathering it will just come loose again.

Thanks

Dave

That type of pipework is normally glued.
Any DIY type of shop will sell the adhesive (solvent cement) you need for the job, don't be tempted to try anything else as the correct product not only sticks two parts together in the normal "sticks" sense but actually melts into the outer surface of the tube and fuses the two parts together.

You'll need to ensure the two components are clean and dry, also ensure that if the rotational position is important they are correctly aligned as once the glue grips no change will be possible.

If not able to dry them well you could use CT1 silicone.

"What sealant can I use on wet surfaces?
CT1 works in wet and even underwater. CT1 is the ultimate product for instant sealing in wet conditions. It can be used not only on wet surfaces such as showers and baths, but it can also be used when completely submerged underwater."

I use it for that sort of thing as it saves worrying about getting the perfectly dry, which is sometimes next to impossible.

Brexiters. It's your sh1t now. Whatever happens nationally and internationally you own it. I wish you luck. I think you're going to need all you can get and then some. Friday 13th December 2019.

Solvent cement depending on its age and age of pipes to connect can be pretty instant. Rehearse the insertion and alignment as you might not get a second chance. No pressure
