Increasing Pump Pressure

[Niloc]

I have a pressure pump in my house, the pressure needs to be adjusted up about 5%,

What is required to do this?

The pump is a "Super Sumo HTC 125 IT"

Thanks for any help

I assume this unit has a pressure cut-out switch which allows the pump to start on a pre-set low pressure and then shuts down on a pre-set high pressure.

If this is the case, it might be possible depending on the switch design to re-set the upper pressure. Alternatley you might be able to fit a different pressure switch with a higher setting.

A word of warning, the blue pipe used for water service in Thailand doesn't have a very high pressure rating - exceed it at your own peril.
