In situations where the cold water storage is likely to fall below an acceptable level, a water starvation protection kit can be used. This will protect the pump from running dry and causing failure.
The Water Starvation Protection kit can be fitted on the opposite side of the tank to the ball valve and is suitable for use with up to 2 pumps.
The WSP is a Salamander Pumps level switch which must be positioned 102mm higher than the highest outlet from the cold water storage cistern. When the water level drops too far the WSP will switch off the pump until the cold water storage level is recovered.
