Spa
and Hot Tub Winterizing Instructions brought to you by Hot Tub Information

WINTERIZING
Winterizing a spa
or hot tub if done properly is a complicated procedure. It is my
opinion that it should be done by a spa
/ hot tub service center, that will guarantee that you will not have a
freeze up, or if you do that they will repair all damages done by the
freeze up at no cost to you. A frozen spa can be very pricey to fix.
With that in mind here are some basic
winterizing tips. Keep in mind however that not all spas or hot
tubs are plumbed the same, so please refer to your owners manual and
the dealer you purchased your tub from before attempting this.
What you will need;
-
A wet /dry (shop vac) vacuum.
-
1 to 3 gallons or RV antifreeze
(nontoxic, used in Recreational Vehicles water tanks)
-
Channel lock pliers (16" works
best for most tubs)
-
A funnel or turkey baster
-
Time, expect two to three hours.
Now that you have those things,
-
Drain the spa
-
Vacuum all of the jets
and injectors, until there
is no more water coming out.
-
Remove your filter and vacuum at the
filter plumbing. (Make sure not to vacuum any O-rings up"
-
If you have an air channel, turn
power on , and make sure the pump
(s) are NOT running. (sometimes this can only be accomplished by
unplugging the pumps from the control box) then turn your air blower
on until water no longer comes out of air holes. Then turn the power
back off.
-
Loosen the plumbing connections at
your pump and at your heater. Vacuum any water that comes out.
-
Reconnect the plumbing to the heater,
and the lower of the two connections on your pumps.
-
Add RV anti-freeze to the pump using
your funnel. Most pumps will take approx. 4 oz.
-
Reattach your pump unions.
-
Add approximately 1oz. of RV
anti-freeze to each of the jets. (use funnel or baster)
-
Add RV anti-freeze to the plumbing
that is attached to your filter until it runs out of the intakes in
the foot well of the spa. (This is not possible in all spas)
-
Add anti-freeze to the air channel /
air injectors, this can be tedious but is worth the effort.
In climates that get heavy snows it is a
good idea to place some 1/4" plywood over your cover to help
reinforce it.
Then cover the spa with a tarp, and strap
the tarp down, this will help keep winter winds from getting to your
cover.
In the spring, or when you are ready to
start the tub back up.
-
Turn the power on.
-
Run the jets on high speed for 15
minutes.
-
Several times during the 15 minutes
that you are running your pump, turn your air blower on and off. This
will purge the air lines.
-
Drain the spa / hot tub
-
Put your filter in the spa / hot tub.
-
Refill and treat the spa / hot tub
water chemically like you would during a water change.
