Hi

I didn't realise until yesterday evening that 32mm push-fit pipe isn't
the same as 32mm solvent weld pipe! I've never had cause to tinker
with waste pipe until now.

I basically have at home;
1 length 32mm push-fit pipe (it didn't say at the DIY shop what it was
- I assumed all 32mm pipe was the same!)
1 length 40mm push-fit pipe
assorted 32mm and 40mm solvent weld elbows and couplings and of course,
the solvent. I also have a couple of supposed 32-40mm (solv)
converters that look a bit hat like. In fact it's one of these
http://www.screwfix.com/app/sfd/cat/...46295&id=13473

I have a 32mm (solv) pipe coming out of a wall (existing fitting), and
I joined a 90-degree (32mm) to it with solvent, and then realised that
my 32mm pipe doesn't fit!

I then realised that the diswasher trap I bought is a 40mm compression
fitting - I assume compression is good here for dismantling and
cleaning.

So basically, I need to be able to convert from 32mm solvent weld to
40mm compression fitting.

Can anybody adivise me on how to connect these things up?

Regards,
Mark

Not sure if you know this or not, but compression fittings will
work on solvent weld pipe and on push-fit pipe. So that's how you
mix and match! So you need some 40mm solvent weld pipe to
connect to your dishwasher trap, and your reducer, and some
32mm solvent weld pipe to connect to your already fitted elbow.

Someone else will probably comment on the advisability of using
32mm pipe for a dishwasher - given the fitting is 40mm, I'd
be inclined to try to use 40mm pipe!

I'd be inclined to try and work out what lengths and what angles I need
and get push fits for the lot.

The cost of buggering the job vss the cost of doing the job properly and
the savings and job satifaction and all that crap, rule.

No, I didn't know, thanks for the info. It should be quite simple
then.

I know, I know, but the existing pipe (32mm) goes out through the wall,
and in to our conservatory, where it runs outside - don't ask me why -
previous owner stuff.....

The run inside the conservatory is already boxed in and decorated, so I
don't want to have to rip it all out for this job if I can help it.

The dishwasher has already been running on this waste pipe - I just
needed to change the layout slightly for a new kitchen layout, so
hopefully all will be ok.

Cheers,
Mark

Probably because the conservatory was added after the waste pipe and
the owner didn't want to arrange a different exit for it from the
kitchen.

If you are connecting onto existing pipe of unknown origin and can't
replace it easily, then for that joint, a compression type fitting
would be safe. I've used push fits in the past and found them to
sometimes leak under these circumstances.

Then for the run from there to the new trap(s), take your pick.
Personally I use solvent weld because you can make a neater and more
compact job.

Mark

You need a solvent weld to push fit adaptor.

Or the other way round. I know you've got to take more care with solvent
weld, but once done it's for keeps. I've seem plenty of push fit stuff
pull apart for one reason or another.

I must admit that I've stopped using push fit waste fittings at all. They
have a habit of coming undone at inappropriate times, or inaccessible
locations. I'm definitely one for limiting to compression or solvent weld,
depending on the individual circumstances.

Especially when not supported properly along its length when it gets hot
water down it. It softens enough to allow the weight of the pipe to pull
everything apart.

I never used them to start with for that reason.

Yep, I always use SW, unless I'm connecting onto existing pipework
when I use compression.

Which is why I don't use it.

In the case of kitchen revamps or blockages push-fit is a good idea. :-)

It's only a question of making sure it all fits then marking it before
glueing.

You can cut solvent weld and extend.

Trouble with a lot of push fit is it's thrown together as it will
sort of self align. Until nature and constant expansion and
retraction has its way and it separates. I've not tried compression
fittings for waste though. Perhaps that is the ideal.

Ive got one house and two flats I lease to the council, every three years
they have a new kitchen/bathroom, plus a maintenance contract for the
properties.
So plumbing is on/off like a fiddlers elbow
You would NOT believe what some people put down the sink and bath, with
push-fit it's a simple job of pulling it apart and refitting, be it for a
blockage or refit.
Ive never as yet had a push-fit leak or come apart involuntary but it does
need sensibly placed fixing clips.
I should add that SW is the only sensible option for shower/underfloor type
use, it also makes sense for a plumber or builder to use it, as it's quick
cheep and guaranteed leak free.
(as long as they remember to apply the glue) :-)
