elec shower, please help...

[cammy2207]

Hi. Installing new electric shower. Bottom left rear connection. I have 10mm mains pipe coming through tiled wall and 15mm plastic inlet. Today I bought 10mm comp elbow, 15mm compression elbow and 10x15 end feed reducer. The reducer doesn't seem to fit the elbows. Please help,
Thanks in advance...

Buy a 15mm spigot reducer to 10mm. This will push int the 10mm elbow and bring it up to 15mm. From here you can connect to the inlet.

Why is the mains in 10mm anyway?

You should have run in it 15mm all the way to the shower to give you a better flow rate.

Or buy this:

Connect this to the inlet and run the 10mm pipe straight into it.

MAKE SURE YOU USE INSERTS!!

For an electric shower?

I use 35mm copper, 40l/min flow rate (took the restrictor out the shower)!!!

Brrrrrrrr doesnt half wake you up of a morning though!!!

Ha ha ha. Nice and cold is it? Still I would always run in it 15mm.

I had a plumber in fitted new bath and sunk previously exposed mains pipe into wall and then plastered wall. He left the blanked 10mm pipe sticking out. I sort of thought it should have been 15. And why does the copper end reducer not fit in the 10mm elbow?

Not sure if there would be room after putting that spigot on inlet' its near the bottom. Would a pic help?

 

[Dan Robinson]

Yes.

The 10mm end of the end feed reducer is the same size as your 10mm compression elbow. It is designed for 10mm pipe to be inserted into it.

As Dan and co put me right you'll probably be fine with 10mm pipe as being an electric shower the flow is reduced anyway to allow the water time to be heated. Depends on the power of the shower what flow rate can be achieved at the temperature you take your showers.

I have my utility and kitchen taps each supplied by dedicated 10mm pipe - the measured flow rate would be fine for a 10kW shower @35 degree rise.

From the sound of it the OP has an external reducer.
