Most spa owners change their hot tub's water
every 2 to 4 months. This is primarily because over time, salt
from perspiration and other non-organic contaminants-- the Total
Dissolved Solids or TDS, will increase to levels causing cloudiness or
other problems.
Although organics are destroyed by your
sanitizer system, TDS levels continue to increase over time. But how
do you really know when it's time for draining?
 |
Maintaining your spa water
balance & sanitizer, along with proper filtration will maximize
the time between water changes. Its time to change the
water when the TDS level exceeds about 1500 PPM. These
levels can be checked with
 TDS
test strips. |
Estimating Drain Intervals
Using your spa's
 water volume
in gallons and
estimated
bather load, you
can easily determine the estimated number of days between
necessary water changes with the simple equations below:
|
Handy Formulas
First, divide your total spa
gallons by 3. Divide this result by your Bather Load, which is
the average number of bathers per day. The final result is the
estimated number of days between water changes recommended for a
properly maintained spa or hot tub.
Example 1:
Residential Spas:
Example 2:
Commercial Spas:
Please keep in mind that these
are estimated guidelines only. The formulas assume that your
hot tub spa is properly maintained, and water is balanced and
sanitized. Other factors such as user hygiene and local water
quality will also affect drain intervals. If users shower
before using the spa, water changing intervals will be longer.
Local regulations may govern water change intervals for commercial
spas.

Hot Tub Drains
 |
Most spas have a drain bib (a
plastic faucet) inside the removable access panel. Some spas
have no drain and must be siphoned. |
|
| |
|
|
 |
Most Belize spa models feature
the Easy Drain so that they can easily be drained by attachment of
a garden hose externally. |
|
Flush Your Spa's Plumbing with Every Water
Change
| You do your best to keep your spa clean and
sanitary, but what you don't know is that the INSIDE of your spa's
plumbing system is likely coated with oily film, contaminants &
grime. |
 |
By flushing your spa's plumbing, jets, and heating systems before
each draining with
Spa
System Flush
#MT1028 you will achieve the cleanest possible water
environment. You'll truly be amazed at what this product removes
from an otherwise spotless hot tub.

Use the
Shake-a-Vac
#AC1021 to clean or drain spas, above ground pools, pool covers,
wading pools, fountains and ponds. This is the only vac we have
found that actually starts its own siphon. We were very
skeptical... until we tried it. Now we love it, and we think you
will too. |

WaterSafe
Test Strips
"I keep our spa as clean as possible but
we have kids so these bacteria test strips are reassuring."
Cindy Stevens

Shake-a-Vac
"We use it daily to vacuum gritty sand
from the bottom of the spa. There was no easy way to get it
out before. Although our spa has its own drain, by using the
Shake-a-Vac at the same time it empties the water twice as fast."
