Diverter Valve Maintenance - Sunrise spas Spas Owner's Manual

DIVERTER VALVE MAINTENANCE

If your spa has a water diverter valve, it is important that you conduct regular maintenance on it to
ensure that it continues to move freely and does not begin to leak. The best time to do this maintenance
is when you are doing a drain and refill.
1) If you unthread the cap (2), you can remove a number of parts that make up the moving
assembly. These include the diverter (7), O ring (6), cap (2) and handle (l).The moving handle is
only a hand press fit, so you can take it apart easily.
2) Examine the surface of the diverter (7). If it has any scratches or score marks on it, there is debris,
likely dirt or sand getting into your spa. If you do not stop this from happening, eventually the
valve will seize and you will break off the handle or worse. This type of damage is not covered
under warranty.
3) Sand the diverter (7) lightly to remove the scratches. Clean out any debris inside the body (9).
From inside the spa you will only be able to see the inside of the body (9), the top threads and the
body O ring (8).
4) Examine the body O ring (8). This O ring seals the cap (2) to the body (9). Remove any debris that
could hinder it from sealing properly when reinstalled. Check for areas that are cut or pinched.
Pinched areas may be fixed by placing the O ring in hot water for a few minutes and then allowing
it to cool down. Cut or broken O rings should be replaced.
5) If you remove the handle (1) and cap (2) from the moving assembly you took out, you will be able
to see the O rings (6). Make sure these parts are there. They seal the shaft as it passes through
the cap (2). Do the same inspection/replacement as you did for the body O ring (8).
6) If any of the O rings are dry or hard, you can use a small amount of silicone based lubricant to
make them pliable again. DO NOT use Vaseline or any other petroleum based product on the O
rings.
7) Reassemble the moving assembly and insert it back into the body (10). As you tighten the cap (2)
move the handle (1) slightly to ensure that the cut-out on the bottom of the diverter(7) is lined up
to the sidewall tab that is in the bottom of the body(9). You may want to look at these (2) areas
for reference before you re-install the moving assembly.
8) Tighten the cap (2) hand tight only. On spa start up check the outer cap edge and inner handle for
leaks. Reminder: Never adjust the diverter valve setting while the pump is running. This
puts stress on the internal parts of the valve and could cause breakage or leaking to
occur.
