14 Check-valve cartridge replacement
To replace the check valve cartridges: (ISOLATE WATER SUPPLIES FIRST)
1. Remove all the chromed trim kit parts, see 6.1 & 6.2.
2. This should expose the check-valve housings, see 5.8.
3. Using a 15mm A/F socket undo the check-valve housings (x2), expect some
trapped water to escape.
4. Unclip the moulding from the brass housing to release the check-valve & filter mesh.
5. Clean or replace the parts & reassemble.
6. Reverse the sequence & re-fit the check-valve housings back into the valve-box.
ENSURE PARTS ARE REASSEMBLED IN THE CORRECT SEQUENCE.
