Hydrofix Water Pressure Booster

Free Delivery2 Year GuaranteeBest Price GuaranteeFree Expert Advice
Hydrofix water pressure booster is an automatic solution for both domestic and commercial premises with low water pressure or flow.
The self contained system is compact, silent, easy to install and has a type AB air gap to comply with water authority regulations. Water from the mains or private water supply is stored in the tank which also houses a submersible pump. A built in flow sensor prevents the pump from running dry and automatically re-sets once the water level recovers.
How it works:
Hydrofix Auto
A built in pressure switch automatically starts and stops the pump when a tap or valve on the outlet is opened or closed. 
Hydrofix Vario
Has a variable speed inverter drive. As demand increases or decreases the controller varies the speed of the pump accordingly to maintain a constant pressure. 
►Dry Run Protected
►Inlet Float Valve
►Type AB air gap with 75mm overflow duct 
►Connect directly to mains water supply
►Water Supply Connection: 3/4” BSP
We supply a Hydraulic Kit which fits directly to the outlet of speedmatic controllers and absorbs thermal expansion in the distribution pipework system. It also prevents repeated stop start cycling of the pump in very low demand situations. i.e. dripping taps or ball cocks.
