Do I need separate foot pumps for hot and cold water?

[yerffoeg]

Your help please.

I am fitting in hot water via a calorifier into my plumbing system. The basic sytem is fairly simple - cold water from a flexible tank running to faucets in the heads and galley; mixer taps at the sinks; footpumps for cold water at both sinks.

I prefer manual to electricical devices whenever possible.

My question may be daft, but can I get away without fitting an electrical water pump or more footpumps to the system?

My reasoning is that the hot water system (by virtue of the the fact that it is hot!) may already be pressurised sufficiently.

no, the heat will not pressurise the hot water system. you can still get away with a single pump however if your footpump draws water from the tank and you use a Y-valve to send its output to either the cold tap or the calorifier inlet.

Don\'t think he\'d even need a Y-valve...

If the outlet from the foot pump is plumbed both to the cold tap and to the calorifier, it should work. Both taps closed, pump won't do anything. Open cold tap, pump will pump cold water. Open hot tap, pump will pump hot water.

with a foot pump you normally would just have spouts, not domestic type taps, but if there are taps there already it is exactly as you say.
