Hi, hope someone has experience with this and can help.
The microswitches on my taps are broken and not easy to access. To stop us having to remember to turn the water pump off at the switch I want to fit a water pressure switch- the Whale WU7207.
On the back of the carver water inlet I have two pipes- one from the filter that goes to the taps and one that goes to the Carver water heater.
My question is- do I need two pressure switches- one for the hot feed and one for the cold? Or will one on the cold do both?

Just one pressure switch for the cold water supply. That's why when you turn off the hot water tap it takes longer to re-pressurise (pump clicking sound) than the cold supply as it replenishes cold water back into the hot water tank whereas the cold is a direct feed. Even with a pressure switch fitted you still need to switch off the pump when not in use because if the barrel runs out of water the pump will start up and eventually drain the battery.

OK, thanks, at least I just need one!
What I want to do is be able to use the taps without having to make sure everytime that I or the kids have switched the pump off. Had to replace one pump already this year due to it being left on.

I understand if the aquaroll runs out the pump needs switching off but otherwise can I leave the pump switched on if I fit the switch?

When my water system is filled I leave my pump switch on but I keep a check on my Aquaroll (40L) I also have a 2 gallon container that I top up with if the Aquaroll appears a little low

Fitted, but it's not working correctly. I don't think the pipework is right. There are two pipes from the inlet- I've tried fitting the switch to both. On one, only the cold tap affects the switch. On the other, only the hot. I've taken pics of the pipework- hope someone can advise!

The white box is the water heater in the photos, the water comes through the blue pipes. I'm just not clear which pipe to connect to as there are two?

I had this trouble when I tried to convert from micro switch to pressure switch, in the end I took the wires from one of the taps to as small switch I fitting just under the sink and used that to turn the water on and off.

You will have to remove all the micro-switches if you want to use a pressure switch as the system won't operate by both methods. It's either one or the other.

You don't have to remove them all , they all connect to each other, just move the wires onto the pressure switch by the water pump housing.

There is only two wires.
