used this to change from a downpipe for W/Mch to use the spout , decided to get this 2 spout as may be getting a new dryer and maybe forced at some time in future for a pumped version. Also when fitted noticed it was adjustable

MacAlpine the best waist fittings ever for reliability. As a kitchen fitter I use a lot of these & the potential call backs are massive on a U bend. Generally due to the nature of a u bend there's hot the cold water going throgh it all the time once fitted. Those white plastic nuts relax due to expation & contraction so offten they start to weep.
Often a sink will come with a bag of cheap associated waist fittings that usually leak very easily.
I'd rather budget for one often two of these as there much more reliable.
A day after fitting you'll still get a quarter turn on those nuts after the've relaxed but well worth it rather than being called back for a leak.

Great quality but it wasn’t the simple swap job I expected. The design means it won’t connect to the waste if it is at a height equivalent to a standard trap with minimum extension. I had to use a flexi connector to make it work (which I’ll eventually replace with adapted pipe work when I get time!).

Bought to replace an older version when updating the kitchen, need to make sure the correct metric or imperial sizes were used throughout- our original setup was a mess so decided to sort.

The double washing machine and dishwasher inlets were easy to fit. Remember to remove the internal blanking plugs, these are a neat way to close one or both inlets but have been known to be missed causing problems.

The chap at the desk was excellent . I had a plumping part that needed changing . He found the part checking first by opening the bag .
His knowledge was first class and when I got home it was what I needed .
Where Plumpstop was 1/10 , he was 10/10
Thankyou
