Winterizing and De-Winterizing Your Spa
Winterization Procedure
Important: Damage caused by improper winterization is not
covered under the Strong Spas Warranty.
1. Turn off power at the GFCI circuit breaker before
draining or servicing your spa.
2. Remove exterior panels by inserting a flathead screwdriver at
the bottom edge of the panel and prying out (Figure 1).
3. Attach a garden hose to the drain and open the blue ball valve
(Figure 2). Water will start to drain. You may have some
water left in the spa shell that did not drain. Remove it with a
wet-vac or by hand with a small cup.
Water drained from your spa is safe to dispose of in your yard, septic
system or in a drain. Follow all local/municipal codes and regulations
for disposal.
4. Loosen all large white unions from heater and pump(s) to let
excess water drain from the lines (Figure 3). Your spa may
have more than one pump. Be sure to follow winteriza-
tion procedures for each pump and all unions. A one-
pump spa has 4 unions; a two-pump spa has 6.
5. Remove lowest drain plug on front of each pump (Figure 4).
Drain out any water in pump(s
).
6. After the spa has drained, you MUST also use a wet-vac to re-
move the water from the lines by vacuum/suction. Water left
in the lines and jets will freeze and damage them.
To adequately clean out the lines, place the wet-vac for 10-15
seconds over: each drain (Figure 5); each union (Figures 6 and
7); each jet face (Figure 8); each suction (Figure 9); and the fil-
ter cavity (Figure 10).
See filter removal procedure.
7. After all the water is removed from the spa, jets, and plumbing,
re-insert drain plug into each pump (Figure 4). Tighten all
unions and make sure all gate valves are open with clips in-
stalled (Figure 3).
8. Pour a gallon of spa antifreeze into the top of each pump (Fig-
ure 11) and a gallon into the filter cavity (Figure 12).
9. Replace all exterior panels.
10. Close your spa cover.
