My unicoupler pops off from the faucet, under pressure. It snaps onto adapter tight but will not hold under pressure. What is causing this to happen and what do I need to fix this problem?
Answer Doug, The faucet adapter WD1X1447 may not help, but it won't hurt either, but it is a good idea to replace it.
The more likely issue is in the coupler WD35X194 itself. The locking tabs inside the coupler may not be "seating" and locking onto the faucet adapter. the coupler slide may not be reaching it's full extension and locking the tabs onto the adapter as well. Applying a little grease to the tabs and the coupler slide may relieve the issue, otherwise you'll need to order the Unicouple kit WD35X194
