C/H pump

[versatile75]

if I fitted a C/H pump to my hot water gravity 22mm flow feed and a inline flow switch would I get any improvement in pressure, I'm not after anything like a booster pump performance!! but wondered if it would help overcome the restriction at the shower hose, and if it would work what type of switch would I need to cope with the hot water,
any ideas please ,Roy

So you have a low pressure water system and you have installed a circulator on the hot water but not on the cold, to improve the shower flow/pressure?

You can't use a normal c/h pump for that application.

Hi point 1, there seems to be loads of pressure to the cold but at the moment can't access the mixer supply to check if its mains or not!! but point 2. ok that's why I asked the question, will break out the bath panel as no fixings visible it must be glued in!! and check if there are flexi tails or straight 22mm copper, the pressure is low as the cylinder is gravity fed via a small combined tank that sits on the top, the property being a flat when the shower hose is raised the heads higher than the head of the tank ? mission impossible, will pursue!! many thnks

If you're happy with an average shower fit a leccy one fed off the mains.
If you want something powerful be prepared to shell out.

Ventura shower?

Venturi you mean, it'd never work off a fortic.

Even assuming cold to taps is mains, obviously? What's the reason, if you can be bothered to explain? If not, then not a problem

They still need a bit of head on the gravity side to work with.
The ops got a fortic cylinder in a flat which means his shower head is higher than his cistern.

Ah, wasn't aware of that, thanks.

Was aware of that though

Thanks again.

The cylinder as rightly described is a Fortic and assuming it was installed by a regular plumber, could it ever have worked to supply the shower with any reasonable pressure, I raised the original question re the C/H pump as I am not sure that a regular shower pump wouldn't outstrip the inflow to the cylinder from such a small gravity tank, Cheers Roy
