I had my cold water tank removed going to the bathroom and have now got the cold water coming straight from the mains. Works well and good pressure when the bathroom sink tap is on and even pressure from both hot and cold now so mixes really well. However there is now 2 toilets, 3 sinks, one bathroom, one shower , one washing machine contending for the same supply so real ups and down in terms of pressure in taps. Really bad is when you are in the shower and the water starts to trickle out then go really cold and then hot when the pressure returns from someone shutting a tap or flushing a toilet elsewhere in the house , or when you are washing the dishes, or when you flush the toilet and then the taps in the sink do not give you much water for 1 minute. What have I done ! This is a nightmare and I need an easy solution ! Is there any ? Please help ?
