Can you post alink to these booster pumps

Hi,any plumbers merchant worth it's salt,should have stock of these items.
One thing to bear in mind,is whether the pump is positive displacement,or circulatory. If your feeding to taps,etc,you will probably require a self contained positive displacement pump,with it's own built in sensing switch. These sense when an outlet is opened,and operate the pump,switching off when the outlet is closed,and the system pressure builds up to relief setting.
The plenum or expansion vessel,gives a bit of "cushioning",allowing a quicker response,on opening the outlet,and a steadier increase when closing.
Some of the motorhome suppliers carry such gear,and i can vouch for it operating most of what a normal kitchen/bathroom would have installed,including thermostatic mixer showers.
Don't forget an easy to find,labelled isolator,for the pump,and NO leaks,as it will cycle annoyingly,with a loss of water causing it to run continuously,till it burns out
