Today's install.

If the pipe has not been sized correctly the volume of water traveling to one outlet may be adversely affected if another outlet, on the same run, is opened at the same time.

So shall we go back to the 22mm supply from cylinder to bathroom and then take 15mm to shower

 

[Whn1]

I'm still sure the way I've always done it is correct, so in this case 22 mm straight to the bath first teeing of for sink then basin and shower in the bathroom then reduced after the bath to feed the shower and basin in the on suite in the next room.

Should have added as well, without carefully deburring the pipe you would not get a very happy customer if you design the pipework for 5m/s flow speed.


@whn1: not a problem.


@SafeGasInstall: Not necessarily. But it could indeed be of advance to have individual supplies for every bath room. May well save you the effort of a secondary return. Just depending on the situation.

Quite unlikely someone would use the shower at the same time as another one runs the bath in the same bathroom if there is more than one bathroom for example. Unless it is a huge family squeezed in a tiny bungalow.

You do not need to size pipes for the one in a million case that all appliances in the household are getting used simultaneously.

Not saying that you are wrong. Just saying it is worth to consider if you can safe the material and the customers time and energy just by such a simple trick as downsizing the pipe.

Hahah, it's been a long day, I'm trying to watch football and now because of dirk I've I've got flow rates and litres per minute running through my head. Thanks dirk

Majority of basin taps size is 1/2inch
And bath taps 3/4inch
So 22 pipe should always imho be going to a bath yes 15mm will have pressure but not flow on a correct installation
