Is it easy to replace both the 22mm bulkhead flow and return (central heating) isolating valves, to the underside of boiler casing.
Both of mine have started leaking badly, one more than the other. Have tried turning slot head to remove sludge and gently taping slot head with hammer and screw driver to seal isolating valve. Water still coming out of slot head screw.
Any advice much appreciated.
