I am adding a disabled bath to a downstairs toilet. The existing hot and cold feeds are fed through a mains pressurised system but are only 15mm. I am concerned that the water pressure may not be adequate to fill the bath reasonably quickly.
Is it possible to add a pump to this type of system to increase flow?
No, you cannot fit a pump in a mains system. Pumps are not designed to withstand mains pressure, and anyway, there is nowhere to suck the extra water from. 15mm pipes are standard for pressure systems, and should fill the bath adequately. 22mm is only used (for domestic) in low pressure systems with header tanks.
