Replacing filling loop valve. Advice needed.

[vim1471]

One of the turn off valves on the filing loop of the boiler doesn't turn off fully and lets out a dribble of water also the plastic black lever is cracked of i have to use a screwdriver then i want to top up the boiler.

To replace this valve do i just turn off the mains water, turn off the return and flow valves on the boiler and make sure no water is coming through the sink taps etc ?

Depends on which side is broken. Water side or heating side?

When i turn the valve on, water gushes out. It has the down flow arrow on the valve. Am assuming its the water side ?

Its the lever on the left.

Just turn the water off at the mains dont touch the isolation valves on the boiler, just open a cold water tap when you close the stop cock and when the water stops running leave the tap open as you swap the valve over , ten min job start to finish

can i just replace the valve and use the old nut and olive thats on there rather then trying to prise that out if its siezed and use some PTFE over the olive ?

yes, try and get a new valve with a metal handle rather than plastic , they are cheap rubbish
