Tap before combo boiler

[juliouno]

Hi I am wanting to install a new tap downstairs. Is it possible to attach the tap to come off the pipe between the rising main and the combo boiler. Or does the boiler need to have the main going to it uninterrupted. And therefore I need to run the tap pipe down off the cold pipe, but after it has fed the boiler.

I don't want to damage/ effect the boilers performance.

Many thanks

Should be fine.

If there is adequate flow and pressure then there shouldn't be a problem. Is it 22mm/28mm pipe you would be T-ing off?

 

[juliouno]

I think that it is 22mm pipe. The pressure and flow rate seem to be quite high.

Any one else got an views on this? Cheers

Its quite common to fit a tap before it feeds the combi boiler, meaning some people want an outside tap to the side of the house if its a semi or detached when the boiler is at the end of the house.

How could you tee off after its fed the boiler? Where would you be teeing off from?

 

[juliouno]

I would tee it off the from the cold water ring, after it had fed the boiler.

The difference being?

Experience if ever I saw it.

28mm , be lucky to see 22mm.

Where exactly is the cold 'after' the boiler?

 

[K4Gas]

Basically Juliano, the point your COLD gets to your boiler, is the last leg of any cold water run. All your other taps and cold feed pipes are fed BEFORE it gets to your boiler, so just Tee in where convenient and you'll be fine

12years of it actually steel... seen enough 28mm main distribution pipes in larger properties in my time to ask the question. More common up here I guess, especially in more remote areas where mains pressure/flow can be erratic. Granted 22mm or 15mm is most common and didn't add in the 15mm, so fair enough, my bad.
