Since the temperature cannot be accurately predicted each month, this rule should be followed conservatively. Backwashing Before backwashing, it is important that the pump be turned off to avoid damage to the backwash valve mechanism. For filters with a side-mounted, vertical backwash valve, rotate the handle to unlock the valve, push the handle down as far as it will go, and rotate the handle once again to lock the valve in the backwash position. Make sure that the backwash hose is extended to the desired area, and turn on the pump.
A large quantity of water and debris will flow out of the hose. Continue until the water which is flowing out of the hose is clear and wait an additional 30 seconds to ensure that the filter is properly cleaned. Turn the pump off and return the valve to the normal filter mode by carrying out the above steps except in reverse order. Once the valve is returned to the filter position, open the air release valve to release trapped air in top of lid or tank tops.
Turn the pump on and monitor the pressure gauge for proper operation of the system. For filters with a top-or side-mounted rotating backwash valve, the process is similar, but instead of pushing the handle down to backwash and up to filter, the handle of the rotating valve is pushed down and then rotate to the backwash and filter positions, respectively.
Once all of the trapped air is released through the air release valve and only water flows out, close this valve. The water from the garden hose should be enough to flood the pump and restart the system. Be sure to open the manual air relief valve after the pump has regained its prime to release the excess air from the filter.
Construction Process. Proper Water Balance. Brushing The Pool. The water flows through the pump to the filter, which removes dirt, debris, and if the filter is good bacteria. After the water is filtered, it flows through the plumbing to the heater if you have one and then the salt chlorine generator if you have a saltwater pool.
The clean water returns to the pool through the return jets on the pool walls. A skimmer is the rectangular opening at the top of the pool wall, right below the coping. The water level should generally be about halfway to two-thirds up the skimmer. Side note: You may not have a main drain—they're becoming less common in residential pools, in favor of only skimmers.
This is because for smaller pools, main drains aren't always necessary. Water flows through the skimmer and the main drain towards the pump and filter to be cleaned.
A pool pump generally has a big, round part at the front and then extends backward. That big, rounded part at the front covered by a lid is the strainer pot.
It looks and acts, predictably, like a strainer. A spinning impeller inside the pump pulls the water in from the pool. This water hits the first part of the pump, the strainer pot, which catches any major debris. After the water goes through the strainer pot, the impeller pushes it on to the filter. A cartridge filter uses cartridges—big sheets of polyester cloth or paper folded accordion-style—to catch debris. Some of these filters only need a single cartridge; others need multiple.
Here at River Pools, most of our customers get a cartridge filter with their fiberglass pool. A sand filter is straight-up a tank full of sand. Slotted lateral pipes at the bottom disperse water evenly through the sand to catch debris. The fingers may look like hanging stalactites or overlapping curved shutters , depending on the model.
Dirt and debris are measured in microns, which is short for micrometer—one-millionth of a meter. Here is a list of the different types of water pumps available to help you pick out the right one for your pool. Single-Speed Pump — This is the most popular choice among pool owners because of its inexpensiveness.
It does the job as well as any other type of pumps, making it an efficient purchase. However, this pump consumes more energy; making it more suitable for pools that are rarely being used.
Turning this off when there is no intention of using the pool is one effective practice to prevent the increase of your electric bill. Double-Speed Pump — As what the name suggests, this pump can change its speed from slow to fast. Pools that have spa-like qualities benefit better from this pump; turning your pool into a therapeutic or Jacuzzi-like experience.
Variable-Speed Pump — Unlike the previous pumps, variable-speed pump has more than two speed options to choose from. Fast, moderate, slow, or whatever the pool owner wants, this pump can definitely do it for you. Because of the speed manipulation, it uses less energy consumption than the single-speed pump.
