This kit is designed for use with domestic water booster pumps.  When installed on the pressurised outlet of the pump / pressure controller, it will result in reduced pump operating cycles and also eliminate frequent starting due to drips and leaks. This will prevent premature failure due to frequent cycling.

The included ball valve allows for easy isolation of the pump from the system.

It may be used as an accessory for the pre-packaged Attic 220 PS and Closet 300 PS range of water pressurisation solutions from RVR.  When installed in conjunction with an Attic 220 PS or Closet 300 PS, we recommend that the expansion vessel charge pressure should be set to 1.5 bar with no water pressure in the system.

The kit contains:
  • 3/4" Tee (F.F.F) 
  • 5 litre Varem Expansion vessel LC (for potable water) 3/4"
  • 3/4" Ball Valve M/F or 3/4" Ball Valve F/F with 3/4" x 3/4" nipple
