We have recently moved into our new place, built 4 years ago and it has a standard Rheem electric hot water cylinder. Yes its on the list to replace when we get some capital.
Our issue is the hot water pressure is very low, when we turn on 2 showers, or a shower and kitchen sink, the water flow drops right off.
The cold water inlet has a non return and pressure reducing valve before hitting the tempering valve. I am hoping the problem may relate to muck inside the tempering valve.
So do I have to fully dump the contents of the hot water cylinder down the drain, before opening the union joints on the tempering valve to clean the filters? And is the low pressure just a result of using an electric HW cylinder, though I thought it was supposed to deliver at mains pressure.
TIA
