Hi all,
On my current job (plumbing ,CH/HW) for a loft conversion on a first floor maisonette. I was planning on adding a water accumalator to improve pressure and flow rate. which is looking like a no go due to cost.
I think the route we are going to take is to increase the water main size from the external stopcock. We currently dont know what the size of the water main is. The main comes into the property at the Bottom of the stairs by the front door in 15mm copper then goes around the flat in 15mm.
What I'm struggling to work out is how to calculate what improvement we can add to the flow rate. I appreciate we need to establish the incoming main size which we will be doing. Currently there is 2.4 bar static pressure 0.8 dynamic pressure and 12lm flow rate at the kitchen sink.
There is approximately 5m from the external stopcock to the internal stopcock, it then rises into the loft approximately 5m again, then across 7m to drop down into the kitchen.
I would appreciate any help on calculating what difference would be made by increasing the water main size and changing the internal 15mm to 22mm.
But what I'm really after is a table or book so I can also work it out for my self in the future. I've spent countless hours online trying to find a idiots guide for the calculation/table but have had no luck.
Thanks.
