Is Your Tank Stuck?
HINT:
Water deposits may build up between the canister and the housing on top and make it hard to loosen the canister.
If you try lightly tapping around the top where it screws into the top this will sometimes loosen the deposit and allow you to turn the canister.
If this does not work try taking a blow dryer and blowing it on the top of the unit. The heat will soften the deposits and allow for opening.
Because of the product�s limited service life and to
prevent costly repairs or possible water damage, we strongly recommend that the bottom of all plastic housings be replaced
every ten years. If the bottom of your housing has been in use for longer than this period, it should be replaced immediately.
Date the bottom of any new or replacement housing to indicate the next recommended replacement date.
