If you have an above-ground pool, installing a filter is essential for keeping the pool clean. The most common type of filter is a sand filter. Installing a sand filter can be tricky because of the connections, but with some clear directions, you should be able to install it yourself regardless of your DIY skill level.Here are some tips to install an above-ground pool sand filter.
Prepare to Work
For this project, you need a:
- concrete blocks
- hacksaw and work gloves
- sand filter kit
- an assistant
Shut off the power to the pool pump. The pool pump may be hard-wired, which means it has to be turned off from a breaker. Some pumps may be connected to an outdoor outlet. Detach the cap in front of the pump to release pressure.
Place the Filter and Add Sand
If you are replacing an old filter, use the hacksaw to cut the hoses at the input and output points. Remove the old filter from the foundation, and discard it. You may need an assistant to help you move the filter, since they tend to be heavy.
Choose a flat surface near the pump and skimmer to install the new sand filter. Avoid areas prone to standing water. If there isn't a flat surface available, set the filter on concrete blocks. Add sand to the filter.
Connect the Filter
Soak the open end of the clamp-style hoses in hot water for several seconds to make them pliable. Insert hose clamps on the ends of the flexible hose. Attach one end to the base of the skimmer and the other end of the hose to the pump's inlet port. Use a screwdriver to make the connections tight.
Attach a hose to the pump's outlet port, which is commonly close to the ground. Insert the other end of the hose to the filter inlet port located on top of the filter, and tighten the clamps with the screwdriver. Connect the third hose to the sand filter's outlet port and the other end to the inlet port of the pool.
Reattach the pump cap, restore power to the pump, and flip the sand filter switch to "backwash". Allow the pump to operate for a couple of minutes to purify the water. Shut the pump off, and set the filter to "rinse". Turn the pump on, and let it run until the water clears.
Shut off the pump. Change the filter lever to "filter", and return the pump to normal operation. If you don't trust your skill, or you need a new pool installation, contact a swimming pool contractor for service.
