Blocked return line or partially closed valve. Either of these can restrict water flow. Ñ Mudballs. If the backwash flows are inadequate or chlorination is insufficient over long periods of time, sand can mix with lint, hair, and other debris to form lumps in the sand. These lumps slow the flow of water. Ñ Calcification. If over a long period of time backwash flow is less than needed or the water is not chemically balanced, the filter bed may develop a rigid coating that blocks water flow. Dirt and small debris are getting into the pool from the filter.

This in turn affects how often the pool’s water volume moves through the filter. You want your pool water to be clear and, if a heater is installed, relatively warm, right? So you want to make sure the circulation pump is working properly at all times! If circulation slows or stops, all of your water treatment systems will stop too, and you’ll quickly see a not-too-pleasant change in your water quality. Impeller Pumps can be either straight centrifugal or selfpriming. A self-priming pump can work using only the water contained in the pump casing, whereas the straight pump must have a constant water supply.

Water flows in the top and is dispersed evenly by a baffle arrangement (also called a distributor) mounted below the input fitting. The water Where Can I Find the Filter? You can tell where a filter is located in a pool circulation system by its name! A filter with vacuum in its name is placed before the pump (where the pump creates a suction), whereas a filter with pressure in its name will come after the pump (where the pump creates pressure). 28 42 to 44. æ Monitor the difference between the influent side (shown on the left) and the effluent side (shown on the right) to determine when your filter needs to be cleaned.
