Check all DRV seals

Check drain plug
Check drain plug and seal for wear and / or
damage. Make sure drain plug and seal are
fitted and tightened adequately. If problem
persists, replace both plug and seal.
Check inlet and outlet connections
Check inlet and outlet thread joints. Check a
correct seal has been made with PTFE thread
sealing tape or liquid sealant. Oil-based, non-
setting joint compounds should not be used.
