15mm stop tap between 25mm mdpe and 22mm copper

[emphasis303]

Hello everyone

Quick question

In between 25mm mdpe and 22mm copper is a 15mm stop tap, 15mm copper has been fitted for about 10cm either side to create the connection.

I have an unvented mains pressured system, do you guys think this 15mm bottle neck has any effect? Is it worthwhile fitting a 22mm stop tap in terms of output?

Many thanks

It certainly will affect performance; but I would use a lever valve instead of a stop cock.

Thanks for your reply

Lever valves appear to be cheaper to.

Many thanks

Just like my sister.

28mm plastic pipe to the 3 bathroom property.
Then 15mm stop tap!!!

Did the builder ever engage brain??

I'm siting back until they move in and waiting for the call.

You need a FULL bore level valve.

Full bore lever bought, push fit mdpe to 22mm reducer, thought I had 22mm pipe when I pulled it out was 28 arghh! Back to the merchants tmrw.
