New house waterpump. I got a DAB E.sybox pump. Sure it definitely is not the cheapest, but I now have more water pressure and flow, the pump is far quieter despite being bolted to the side of the house (old one was approx 10M away next to the tanks). And it uses less power. It has also solved the problem of water flow sometimes being low from the fridge chilled water dispenser and the filtered water tap over the sink.
I highly recommend it if you need a new house pump. I will probably turn the pressure down on mine (it is electronically adjustable). As Im no longer putting the shower mixer on max flow - it is too powerful now.
