Hot water issue

[terryplumb]

Firstly to get a pucker supply ,and prove the existing run is the issue. You can then make it permanent ,but you will need to support the pipe with clips , and inevitably that will require taking the" boxing in" apart .

 

[Ches smith]

How far apart can the clips be? There is only about a meter of boxing in until the the pipes enter the corner cupboard. So could add clips above and below the box section.

 

[terryplumb]

If it's only 1 metre ,above and below would be ok , and of course some before and after !

 

[Ches smith]

Perfect. That is my job for tomorrow. The existing compression tee will be okay to use with the PAX pipe won’t it? Obviously with inserts.

 

[terryplumb]

Yes. Cut pipe square ,chamfer edges smooth, fit stiffener into pipe. Compression fittings are fine ,and push fit if you want. I would go all the way from tap to your " new" Tee.And if you use an isolation valve just before the tap ,fit a full bore one,if you haven't already.

 

[Ches smith]

I assume it’s always better to go for a full bore valve

 

[terryplumb]

Every little helps !! The internal bore of plastic pipe is less than that of copper tube ,but on mains pressure it doesn't usually make that much difference ,but I suspect your mains pressure may not be great. Oh ,and get rid of all the elbows if you haven't already.

 

[Ches smith]

Excellent thank you. I shall let you know the outcome.

 

[terryplumb]

Please do.

Hello all. I’ve had a productive afternoon. Replaced the 15mm vertical copper pipe with PEX. Into the 22 x 15 tee from the main hot feed. No leaks (so far) and we have hot water in the kitchen.

In the boxed in section the pipe had a straight coupler followed by an isolation valve. Having looked through the pipe I removed there is either a blockage or the isolation valve is faulty. There is no daylight at all.

Thank you Terry and Chris for all your help!

You’re welcome, probably more Terry than me, but you got what you needed

Well done Ches ,thanks for letting us know the result.
