Solvent Weld Pressure Pipe

colin H · 24 Jun 2013

I`m currently installing a new filter for my garden pond .

I`m using grey solvent weld pressure pipe to make all the conncetions . Ive cut most of the pipework and fitted it "dry" to make sure Its all in the right place Ect .

The jointss seem very tight when I assemble them and its difficult to get the pipe to in the full distance . Im a bit worried it might be difficult to work with when I finally solvent weld it .

Does the application of the solvent make the joints any free-er

I`d appreciate any advice you can give me on this

Get some light sand paper and remove any burrs from the ends of the cut pipe. I guess your using a saw blade which leaves the edges rough and the pipes are hard to put together.

If you use a good pvc pipe/cutter blade no need remove burrs. Just be careful you don't crush the pipe.

Hope this helps Robiow

Yes. It acts as a lubricant and also dissolves the surface of the pipe and fitting, making it easier to assemble.

Read the data printed on the pipe (ABS or uPVC?) and make sure you get the correct solvent-weld adhesive and cleaner. The 'multi-purpose' stuff is inferior and won't take pressure.

ABS becomes brittle with age outside and should be painted, insulated or otherwise shielded from sunlight.

What onetap said.

Use dry emery cloth to clean the pipe and fittings, not sandpaper.

Apply the adhesive to the pipe and inside the fitting and push together with a slight twisting motion.

Have you got fish in the pond, ?

I would Check that the solvent will not affect them, or let the pond/filter settle for a few weeks before putting fish in.
