Low water pressure - any thoughts?

[rocketmanbkk]

Hi Friends

Woke up today to low water pressure in my house.

It's a direct fed system with a combi.

Cold is @7lt per min now.

It happened last Oct but righted itself and now gone again.

Nothing changed, checked Thames Water, no works or leaks etc.

Any thoughts?

Thanks

All good, toilet fill valve whining under the pressure. I've closed stopcock a bit. All good.

change washer should sort the noise
