Shared hot and cold supply to sink and shower in ensuite

[seftonbarn]

I am preparing my new en-suite pipework for connection to hot and cold tanks by my plumber (at the same time that he fits a new boiler). Does Building Regulations allow me to "T" off the shower hot and cold supplies to the sink?

It is just that the ensuite is tiny and there is no way that me and the Mrs will be in there at the same time so therefore there would never be a situation where someone is using the taps on the sink at the same time as the shower was in use. The Mira Mixer that I have for the shower has a temperature safety device so that if cold pressure drops the shower shuts off.

I appreciate you advise.

Gravity supplies? Is there a pump?

The connections that your worried about is when the plumber connects onto cold water storage tank , the hot water must be above the cold water outlet so that the if a problem occurs the hot stops first then u get a cold shower but if wrong way round the cold would stop and you'd get scalded,

If it's gravity system then you should have seperate feeds for the shower and the basin , if you have on the same feed then it will cause pressure variations when another outlet is opened,

Gravity supplies. No pump.

Thanks for your advice. I understand this. But in practical terms there will never be more than one person in the room (it's tiny). I am happy to have a shared supply to the shower and basin but my question is does this meet with building regulations? I realise it is good practice but is it legal.

How high from shower head to base of water tank in loft? Thermostatic mixer?

I guess 3 metres from the cold and 2 metres from the hot. Why's that?

So would a shared supply contravene building regs or not?

It will be a pith poor shower which will go to next to nothing if a hot top opens somewhere else in the house.

If doing something, do it properly first time.

I live in a bungalow with an existing gravity fed shower in the main bathroom. The shower has no pump and is perfect. The new shower will also be perfect because it will be a separate take from both hot and cold water tanks. I would like to avoid running separate supplies to the sink next to the shower; there will be no problems with pressure fluctuations because there will NEVER be 2 people in the new bathroom. Please can someone answer the simple question if this contravenes building regs. I don't need any other advice or opinions.

No thanks. As the advice is not available on this forum I shall just crack on and have a shared supply to the new ensuite. An english man's home is his castle and all that.

Could always ask your 'plumber', just a thought.

I don't need to ask my plumber. I shall TELL my plumber what I need him to do and have decided the correct way ahead. If I did need a plumber I wouldn't be choosing SimonG. Ash tray on a motorbike and all that
