Filters
Water World carries a large line of spa cartridge filters. Be sure to
measure your filter height, diameter and size of inner hole prior to
purchasing a new one, or bring your old one into our showroom
and we'll be happy to help you.
Follow the guidelines below regarding cleaning and replacement procedures.
When to clean a cartridge filter
Cartridge filters work on the "clarification process". They
utilize the debris they collect as an aid to improve filtration. As a result,
cleaning too often does not allow the filter to work at optimum filtration
efficiency, while not cleaning often enough will shorten the life of a
cartridge element.
When you replace the element with a new one, note the start-up pressure on
the tank gauge. This reading is the system's total pressure in "pounds
per square inch" or PSI. Mark this point with a drop of fingernail polish
or a grease pen. Then add 8 pounds to the reading and place another dot. You
now have the normal operating pressure range for your cartridge. Allow the filter to
operate between these two points and clean whenever the gauge reaches the
higher pressure mark.
When to replace a cartridge filter
Cartridge elements do not have a defined expiration point. Instead, the
fine interstices of the media matrix gradually plug up over time. In a typical
spa, the culprit that plugs the media is perspiration and body oils combined
with soaps, chemicals and very fine particulate. In a swimming pool, the
loading is primarily debris along with sun tan lotions and organic matter such
as algae.
Assuming the filter is properly maintained and correctly sized to the pump,
determining when the cartridge is exhausted depends primarily on three
factors:
-
Shortened cycle time between cleanings;
-
Low water flow rate and high differential pressure;
-
Catastrophic failure such as a tear in the media or a centre core
collapse.
All three are dependent upon proper pool or spa water chemistry and
following a routine maintenance schedule. Homeowners should be reminded that
filter elements are plastic and should be handled and maintained accordingly.
Here are some suggestions to maximize the life of a cartridge:
-
Clean the elements according to the cleaning instructions that came with
the cartridge.
-
Never use a stiff brush to clean the media.
-
Maintain pool or spa water chemistry in proper balance.
-
Do not allow the operating pressure range (see above) to go over
8 PSI between cleanings.
-
Alternate two sets of cartridges when cleaning.
-
Use an enzyme treatment to break down oils.
QuickDrain™
QuickDrain™ is an inexpensive and easy-to-use way to spot vacuum hot tubs,
spas, pool covers, wading pools, fountains, and virtually any above-ground
water container. Quickdrain™ is a hand-held, self-priming siphon that
vacuums as it drains. Virtually clog-free, Quickdrain™vacuums gravel,
leaves, sand, and other debris quickly. The siphoning action drains the water,
creating suction to vacuum the debris from your tub. When Quickdrain's
discharge hose is placed lower than the bottom of your spa, a few quick pumps
of Quickdrain starts the water flowing.
With Quickdrain™ speed is a virtue, especially during cold weather
conditions. When using Quickdrain you can expect water to drain at an average
of 10 US gallons per minute. And Quickdrain's 24 feet of discharge hose allows
water to drain a good distance from your spa. If you would prefer a greater
distance, just pick up a Quickdrain Extension Hose Kit to increase your
options 24 feet at a time. Whether you add 24 or 240 feet, Quickdrain provides
the flexibility you need.
