Gravity fed water system
Two copper pipes in bathroom cupboard which have stops cocks which turn the hot and water supply to the kitchen/bathroom off and on. No stopcock under the kitchen sink.
Morning everyone, just trying to figure out where do single/double check valves normally go when connecting to the water supply pipework and what is the purpose of them?
I have a single/double valve fitted on pipes near the toilet and am trying to figure out how many is the norm? Do I just need one or more connected in the flat such as to the bathtub/basin pipes or even the kitchen sink cold/hot water supply.
Lastly when I use the washing machine and it is doing a load, water comes up into the kitchen sink, is there a reason for this and anything which can be done to prevent it as I took apart the pipes under the sink (white plastic ones) and they were clean no gunk or blockages.
Thank you for any info/advice
