Hi,
I've always had reasonable hot water pressure in my house from a hot water tank in an airing cupboard in the bathroom fed from a plastic cold water tank above it in the roof space.
I have replaced the sink in my kitchen, I now have one of those swiveling mono taps which is connected to the hot water pipe by a flexible braided tube that has a smaller internal diameter than 15mm copper. There's also an inline mesh filter.
The flow of water has been reduced from a reasonable gushing to a barely useful trickle.
I could fit a pump to boost the pressure but then it's just more electrical power to consume and it will wear out and break down one day.
So, why not improve the head to the tank? The cold water tank in the roof is resting on wooden beams across the rafters. What if I raised the height of the tank by placing more beams on the existing ones. There's only a few pipes going to the tank and it's made of plastic, so it would seem to be an easy job.
Does anyone know a formula to give the head from a known height. Eg. how much higher would the tank have to be, before I notice an improvement in the water pressure?
Thanks
