Our Hymer has a standard submersible pump but would like to increase the pressure and install a shurflo pump. Can i find a good place to install the pump and just take a inlet pipe to the tank and then reconnect the outlet pipe that feeds the taps? Also just keep the taps running on the switches?
Many thanks..

With a pressure pump you need a permanent 12v supply.
The tap microswitch wires aren't up to the job for a pressurised pump.
To be safe I would fit a stub with sealing washers in the tank side and connect to that to minimise leaks

Are you confident that the system can handle the inreased pressure?

No im not sure it can handle the pressure to be honest just wondered if anybody had done it on a hymer!
What do you mean John a sub with sealing washes..
The pump in the moho is new but not happy with he pressure especially in the shower.
Is there any alternatives?

Something like this.....
Of course, you need to get a hand in the tank to fit it.
