I have recently bought and installed a Fluidmaster Bottom Entry Fill Valve UK ½". I have used this valve many times and never had any issues, and it does state on the description that it works well with high or low pressure.
It is working fine but the problem is it makes a lot of noise when filling up as there is a lot of pressure. It does have an isolation valve which I closed slightly but did not work.
I was wondering if anyone had any tips or could recommend what they would use in regards to a flow restrictor ?
Thanks
