Low Pressure....

[liam546]

I have recently bought a Victorian property which has shared access to a water supply in the back garden. So as I understand it there is a T pipe off the mains which supplies my house and next door.

Using a measuring cup (not sure of correct name) I get a reading of 14. My main aim is to get as higher pressure and flow rate as I can as I would like a decent shower.

It is a blue pipe coming into the outside stopcock (25mm or 32mm). I'm looking at a pressurised system as a combi is expensive and from what I understand a pressurised system is the way to go.

My question is how do I ensure I can get the maximum pressure and flow rate from my setup?

Weell seeing as you asked so nicelyi suggest you learn the difference between pressure and flow.

I realise now, that the reading I took of 14 is the flow rate.

How do I measure the pressure? And would you sa 14 is good enough for a pressurised system to give a good showering experience?

Sorry for sounding simplistic but you need a pressure guage


14 LPM is not really good enough for an unvented cylinder,you will need to look into a mains upgrade

Also test the flow rate with two taps open and see what you get

I will be considering a my own new connection if once I've fitted all the new pipes and new cylinder I am not happy with result. If I put say 22mm pipes inside running up to cylinder and to bath and shower I guess I could do mains upgrade at a later date if still not good enough right?

Also....what's the logic of trying the cup with two taps running. I'm assuming I could well get a lower reading. I should probably mention it's a 2 bed with 1 bathroom, 2 people living in the property

My understanding of the logic is, that if you're taking a shower and someone opens a tap, you don't want your shower to reduce to a trickle
