Internal waste fittings: push or solvent weld

On drainagepipe.co.uk, while reading the support and instructions page (for me, rare, I admit) I bumped into this ;

INTERESTING FACT

Push Fit Waste systems are far more popular in the North of the UK, whilst Southerners seem to favour Solvent Weld Waste!

Theres a support video too: punch line : " The choice is yours"

Does it matter then? I suspect not ... 

 

And if that's the case then isn't it an argument for Multifit ? 

I think @pocster   (?) and I should use Pushfit maybe?

Neither for me, i prefer the compression screw fit ones. Once had a push fit under the sink, which slowly worked its way loose, until one day we pulled the plug out the sink, and i'm sure you can guess what happened!

So there's three types ....

For me I mostly used push fit for the 110mm with some solvent weld where things were a bit tight (often a SW fitting is a bit smaller than the same push fit)

 

For the smaller stuff, 50 / 40 / 30mm I use solvent weld except for things like sink traps.

I love solvent weld, I use it for most waste runs and use a compression where I need to have the ability separate something or may need into it. You cannot mix solvent and push-fit without the adaptor pieces or a compression fitting. I did a lot of push-fit waste years ago and compared to solvent weld it feels a bit inferior. 

 

I always put in screw in blanking ends too - T here and there with a plug seems like a good idea for getting in in the future for blockages, I also always try and engineer enough pipe between tight joints so that if needed, I can cut it off hard up against the fitting I am removing and still have enough of a stub of pipe left I can weld another union on.

One advantage of push fit 110mm is when "someone" changes the position of the toilet, it's easy to undo it and move it.

I was meaning when at the last minute SWMBO changed the layout of our en-suite.  And before that, changed the layout of the main bathroom.

 

By the time I got to solvent welding the bath and basin waste, the layout was set in stone (or set in welded PVC)

I was being facetious....

I've grown to like solvent weld. Secret is to dry assemble everything and put alignment marks so you can reassemble it quickly and accurately with the glue on. Don't be too mean with the glue either.
