20mm MDPE to 22mm copper??

macka09 · Dec 12, 2017

hi all. I need to a stop tap for 20mm MDPE to 22mm copper but it's doesn't look like a brass tap is available. What's my best option? Not that clued up with mdpe fittings to be honest.

I'd get a Plasson 20mm - 22mm coupling, short length of 22 copper and then a 22 stopcock.
Simples.

I did think that but then I've got a fitting before the tap which could blow. Also I've never used Plasson fittings. Do Philmac do this size coupling?

Ok so get a 20mm plastic stopcock, then a short length of 20 mm mdpe, then the Plasson 20-22.
Job done. Nothing wrong with a Plasson fitting but I'm sure philmac will do one.

Philmac don't actually do a 20-22mm coupler believe it or not. I've never used Plason before only ever philmac. I picked up a 25mm tap with the reducing sets but couldn't do the job as the floor layers were there.
