How do I clean feeder pipe to hot water tap?

[Deleted member 267285]

I think further investigation is required.

Totally agree. I’m thinking there maybe a restriction in the cwsc outlet, or even a faulty float valve - depending on when the bath is ran. We use hot water all day and bath the kids at nighttime.

Running the other hot taps does not affect the flowrate of the hot bath tap.

BUT, my bath taps are 1/2", I'm thinking now they should be 3/4"?

Is this the problem?

Bath taps should be 3/4", although the supplies can be reduced down to 1/", depending on setup. If fed from gravity supply, I'd expect the pipework to be run in 22mm from cylinder/cistern to taps, otherwise if mains/unvented cylinder or Combi boiler then both supplies in 15mm should suffice.

What do you think is 1/2 inch ?
The supply pipe ? ( possible )
The thread of the tap tail ( not likely )?
You have told us that the hot water is gravity fed ,is the cold to the bath tap also tank fed or from the mains ? And how does the cold flow compare to the hot on bath tap ?

I bet a bit of foam from the hot water cylinder is in the 22mm section of pipe work.
