Hi,
I would appreciate some advice please. My son has just bought an old rather large house. There are two pumped showers fed from a gravity fed cylinder. The distance from cold header tank to cylinder is about 10 metres (22mm pipe). From the cylinder to the first shower pump is about 25 metres (22mm) the run then continues about another 20 metres to the second shower pump (22mm).
I would estimate the total head to be about 3 metres (the header tank is on an 18 inch platform in the loft and the room height is about 7 ft 6. The problem is that when either ofthe showers is used they run for a minute or so and then start "hunting" and the water delivered slows to a trickle.
Now the elegant solution would be to shorten the pipe runs by re-siting the tanks, but since that would be major surgery, is the current pipe of a suitable size for this configuration? Would it be possible to increase the flow to the pumps by siting a third pump in the cold feed to the cylinder in order to boost the total head?
Any advice would be greatly appreciated
thanks
