Moving a radiator

[Madrab]

It's a different type of push fit than say JG or HEP that are easily demountable. Used to fit lots of myson bits, it's what we were supplied with.

Just push it in all the way and pull back on it to ensure it grabs properly and it should stay there quite happily. A wee trick, wet the end of the pipe and the insert before pushing into the fitting, I use a bit of spit ( I know I know) but it gives it that little bit of lubrication to get the insert and pipe past the o ring inside without too much effort.

They give you the insertion depth in the instructions, so measure 23mm, Mark it, fit it and check it

Thank you so much guys! Your advice has made the difference between me not having a cliue at all and actually feeling comfortable to do the job!

A little follow-up question, if I may!

It has been mentioned that the following fittings are reusable:

With the system drained, could I just push-in the white collar and pull out the hose, without cutting it off?

 

[CBW]

Yes, that’s how they should separate. Sometimes the insert gets stuck though.

I really appreciate your prompt response, Chris! Thank you!

You get 2 types of 10mm push fit stems

The ones you linked to, in the post with the pegler instructions were the former that need to be cut off, the first pic of your rad valve was the latter type that are demountable.

Thank you Madrab! A very important clarification!

I am so sorry to keep coming up with more questions! The Mrs has raised the stakes by suggesting that we hide some of the pipes into the wall. I have a very rough sketch of this:

One question that I have is: how bad would it be if the 15 mm flexible polybutylene hoses form a bit of an arch within the wall (area circled in yellow)?
I think they will need to go up a little bit, to then come down from the radiator faceplate. Would it create any problems for the water flow?

Thank you for your ongoing support!

 

[Madrab]

As long as the pipes don't kink then there should be no impact to the flow.

Your pic shows a vertical " designer" type radiator. If that's what you intend to fit ,be aware that some must have the flow and return into specific sides of the radiator.

Funny though, just shows you how good some installers can be, that pipe guide is on back to front, they would usually recess into the wall with the seals at the top, not sit proud of the wall

If it is a Manthorpe GRS-FF, which it looks like it is, then it is meant to fitted on the surface - here are the instructions.

Don't be - that's what forums are for!

Are you extending in 15mm, or sticking to the 10mm as per the current pipes? 15mm would likely require cold-formed bends to help it bend without deformation in what looks like limited space, but 10mm is far more flexible.

Thank you for highlighting this! I somehow thought that the smaller ones are 15mm.. nearly added the wrong item to the 'To Buy' list!

Thank you Rob, that's great to know!
