Pipe Diameter Advice

[securespark]

Oh dear. The more I look at what this plumber has done while we have been away, the more my heart sinks (See also post about stone resin tray).

The old bath hot feed and the thermostatic shower (gravity tank / cylinder-fed) were all piped in 22mm.

The plumber has run the new feeds in 15, despite all three being further away than the originals.

They should be in 22, shouldn't they?

 

[Terry lambert]

Yes, they should be in 22mm.

Sorry mate not much more to add to that

Unless he fitted a combination boiler.

Ditto..

I can't think of any reason why he would use 22mm, apart from the price.

 

[Terry lambert]

As doitall said if your going to fit a combination boiler it is correct.

If your keeping your hot tank gravity system as stated it should be 22

I can't think of any reason why he would use 22mm, apart from the price.

Maybe because he doesn't understand gravity systems.

Exactly, if you have to put 'a' pipe in, you would use the cheapest.

If you don't know what your doing.

it would depend gents, if the tank is 3 storeys up and the plumbing in the basement I can't see it being an issue...

I know that sparks are very well paid, and Cheshire is very posh. So, Secure, do you live in a 3 or 4 storey mansion?

Thank you very much guys.

There is no combi, just an old Ideal Mexico from 1982.

We have a two storey early 60's det house. The bathroom is on the first floor and the shower head is not much below the bottom of the tank (around a metre), so I have bought a Triton Tesla 0.1 bar thermostatic mixer shower.

As far as I'm aware, it is gravity fed, what with the tank in the loft and the cylinder below, but it's not a bog-standard system because we have some three way ports or valves under the floor near the cylinder: however, this won't affect the size of pipe needed for the shower, will it?

SS get a booster pump
jeez man 1m is minimum (and that was hard to do on a sunday )

 

[securespark]

Cheers kev, long time no talk, man, how's thee keepin'?

I did mention a pump to the plumber and he said it would cause more problems than it would solve.

Mind you, on the basis of what I'm finding.............

 

[kevplumb]

No, those control the flow of heated water from boiler, and tell it whether to heat the cyl, rads or both. Nothing to do with the clean stored h or c water.

 

[Whitespirit66]

he said it would cause more problems than it would solve.

Maybe he was talking about himself.
