RO Booster pumps

[mr_alberta]

Can anyone recommend a nice and quiet RO booster pump? My parents Aquasafe unit isn't getting enough pressure (<40 psi) so I need a nice compact booster pump to increase the pressure.

Also, do booster pumps come with some sort of on/off switch or valve that turns the pump off once the storage tank is full? Or do you have to buy a separate attatchment for the pump and rig it up?

Thanks!
