ENTREE BATH LEAK GUIDE
Note
: Leaks can be cause by one or more of the following.
•
Foreign debris or material between seal and inner stainless steel door skin:
This generally occurs right after
installation. To correct: rotate the door to access the seal area. Use a plastic spatula or similar non-metallic tool with
cloth over the end to clean any debris trapped between the seal and stainless steel door skin, or using a wet-vac with
crevasse tool, clean along the entire length of the seal with the tool directed at the area between the seal and the
stainless steel inner door skin.
For better access, see
Entree Door Seal Diagram page 46
•
Water overflowing above the level of the seal inside the door:
A combination of full BathAire
(SM)
volume and/or an
active individual you are bathing can cause water to run down along the outside of the seal making it appear the seal
is leaking. To correct: reduce BathAire
(SM)
. Adjust the fill level of the tub down to one to four inches below the
overflow. Calm the bather down.
•
Diverter Seal worn or missing.
•
The casual water drain system is not functioning:
The casual water drain system is designed to drain off any residual
water or water remaining between the tub and the seal when the door is first opened. If this system is not functioning
correctly, water will run out one side or the other of the lower end of the fiberglass door cover when the door is
rotated to a full up position.
This failure can be caused by two events:
o
Check valve stuck or plugged with debris. To correct: check and clean the valve.
o
The check valve in the 2” PVC drain pipe is located too high above the level of the hose barb in the door when
the door is rotated to a full closed position. To correct: relocate the check valve in the drain pipe to 2 ½” above
the floor. Plug the hose at the previous position of the hose barb.
•
Seal not being compressed enough:
The adjustment for proper seal compression is made at the factory and will not
normally require further adjustment in the field. The seal is perfectly round when the door is open. When the door
is in a full closed position, the seal should be compressed into an oval shape about one half its original size.
If not, two things can cause this:
o
The attendant is not holding the door close switch down until the door rotation stops automatically. To correct:
make sure the attendant is holding the switch down until the door rotation stops automatically.
o
The seal is flattened and unable to compress
further. To correct: call MasterCare to order a new seal and
replacement instructions.
•
Seal is worn out or damaged:
Three things can happen to cause the seal to fail:
o
The round shape can be altered through prolonged compression with the door fully closed for an extended period
of time. Check the shape of the seal with the door open. If it is in a very obvious oval shape, it has been damaged
by prolonged compression.
o
The seal has been damaged by a cut or gouge in its outer surface. Check for this type of damage.
o
The seal has lost its elasticity. The seal should spring back to a round shape immediately after decompression. If
not, it is worn out and it will not seal properly.
To correct any of the above situations, replace the seal.
CAUTION: DO NOT compress the seal (close the door all the way) when tub is NOT in use.
Leaving to door closed when not in use will decrease the life and quality of the seal and should be
replaced
.
