Two decades under the sink, distilled into simple fittings

We spent the better part of twenty years fitting taps, showers and cisterns in other people’s homes. The same thing came up again and again: most homes run far more water through the tap than anyone actually needs, simply because the fittings were never set up for it.

Dwph takes the small, unglamorous parts a plumber reaches for — aerators, restrictors, displacement hardware — and packages them so anyone can fit them by hand. No call-out, no fuss.

We’re deliberately honest about what these parts do. They reduce the flow rate of water. We don’t put a number on money or litres saved, because that depends entirely on your home and habits — and we’d rather under-promise than mislead.
