20mm to 22mm reducer

[Irish]

Evening all
does anyone know where I can get a 20mm mdpe to 22mm coupling ??
thanks

You would be best getting a 20 - 15 mm copper then a reducer. Or in your case an increaser!

MDPE, PIPE & COMPRESSION FITTINGS

20mm to half inch female and then half inch male to 22mm

PIPE FITTINGS - UK COMPRESSION

code 9860 for the mdpe fitting

code 7812 for the compression

Yeah that's what's there at the moment chalked it's restricting the flow for a mega flow

How about B.E.S or even our own Williams&Co.....regardsTurnpin

as the half inch fitting will again be a reduction in size.

if you could cut it back the 20mm a bit you could remove the restriction by

fitting a 20x25 mdpe reducer
short bit of 25mm
then a 25mm x 15mm/22mm straight connector onto 22mm copper

Polyfast 40625 reducing coupling with a 46420 20mm poly insert in the small end and a 46825 3/4 x 22mm copper insert in the fat end.

Ugly, but will do it in one go, and shouldn't restrict the flow.

Yeah that's what I'm trying to avoid 1king not much room behind the dishwasher ! Can't understand why them feckers can't design a slight less deep d/w so a bit of pipe work can fit behind them

i think ray just sorted you the best solution out

A philmac 21-27mm x 25mm transition coupling with a 22mm copper insert.

Btw it won't do any good it is the 20mm pipe that is restricting the supply.
20mm pipe has a wall thickness of 2.4mm so the ID is 15.2mm. Stick an inset in and you are down to around 12.5mm.

Had just arrived at the same conclusion, having searched the kuterlite 700 range, suddenly twigged why they didn't make one. Answer - because it would be pointless.

Yeah ok lads thanks for searching and answering, much appreciated

i had a bag of imperial or thing someolives in my van somewhere, some were 20mm in sure, i flare a piece of 15mm pipe as a insert, pop it into the 20mm and then use a 22mm compression coupling with the 20mm olive inside it, if i rememper they were like really thick olives, buth then again if i use a 15mm pipe as a insert , there would no more water than a 15mm pipe come thru it!!!!
