This gives the best performance in our pump range when you have low pressure hot and you have low pressure cold. It was originally  used for gravity hot and cold systems but it is great in any plumbing situation where you need to protect and boost the hot and cold to any tap or shower. Combi Boiler systems and unvented systems are often introduced into a homes to solve pressure problems however we sell lots of pumps to customers who find individual showers and taps suffer when other taps are turned on. If this effects hot and cold pressures then it is the SP22S you need.

The SP22S is a two pump kit consisting of automatic SP2B pumps which are fitted to the hot and cold pipes and linked by electrical cables cables so when a hot or cold flow switch is activated by turning on a tap or shower both pumps run.

The SP22S comes with free 22mm to 15mm adaptors so you can fit the pumps onto 22mm or 15mm.
It includes a single 3 amp transformer which plugs into a 3 pin socket.
It includes a very detailed fitting guide
You can fit it to boost any pipe by cutting out 110mm of pipe and connecting it with the pumps DIY friendly compression joints.
