    A defective or leaking non-return valve can lead to an absolute vacuum in the pressure line. When the pump is started, water moving at very high speed fills the cavity and hits the still moving water in the pipe above, creating water hammer. Impact can split pipes, break connections, or damage the pump and motor.

    How long do pool check valves last?

    Pool valves typically last 5 to 7 years before external plastic parts need to be replaced. While the details of the inner surface are working, the handles can be replaced. If older model valves are over 10 years old, you can replace the entire valve by simply replacing the handles.

    The non-return valve is designed to force water to flow from the pipe in only one direction, and to prevent gravity from draining water into the filter, pump and hoses when a new pump is stopped. They are also used to fill raised spas, fountains, or water heaters with rainwater when the pump stops to prevent gravity flow. In fact, pool valves can be used in other ways, see below.

    How do you know if a check valve fails?

    Symptoms of a Faulty Check Valve For example, frustrating check valves will start to wobble and even lose some of their internal fasteners if something goes wrong. Other symptoms of a bad check valve can bereverse flow, excessive slippage and component damage. Check valves make noise when they immediately begin to break.

    The most famous use of a check valve is to hold water in a human pump when the engine is immediately stopped. One such common point for a check valve is the suction inlet before the filter pump. For better priming of the pump, especially in pump systems located more than 24 inches from the water surface, a check valve should not be installed directly at the pump inlet, but at a distance of 12 to18 inches in front of the pump. They can fill not only the basket, but also a full-fledged hookah.

    If there is no room for a sight valve at the horizontal point where the line enters the pump, you can install valves on the up and down suction line or on a skimmer with main discharge pipes. As a result, however, you must install check valves on all vertical suction pipes, unless the pipe normally has a closed valve, such as a hot spa drain pipe.

    For pools that are winterizing their system, installing the pay valves vertically on the suction lines will prevent ambient air from flowing back through the skimmer and main drain lines. There is also the concern that moisture will accumulate above a suitable vertically mounted check valve. Installing PVC fittings directly below the vertical valve will solve the problem and/or completely winterize the suction lines. Another option is to move the pump further away from our own inlet valves and/or change the suction configuration. manifold to add a more horizontal direction to fit a single search valve between the pump and almost any suction line valves.

  • The pump check helps to quickly catch the underground pool pump valves by keeping water out of the pump and filter when the pump stops. This ensures super-fast priming of the pump during long motor run times and also prevents pool filters from clogging or debris from entering the pool when the pump is normally off. Check valves are generally not used in above ground pools where the equipment is located below the water level, which is called “flooded suction”.

    Solar pool heater

    pool check valve troubleshooting

    Rooftop solar pool heaters can inspect supply valves and pipes. A non-return valve in connection with the pipe leading to each of our solar panels allows you to avoid emptying the solar installation when the pump stops at a minimal cost. Prevents water from flowing back through the solar panels after being turned off.Solar installation values.

    In order for pools to winterize their system, you can install PVC work bands on both sides of the inspection valves so the system can lower and/or blow out the solar panels more securely. The new Jandy, Pentair and Waterway check valves are serviceable and can be easily opened allowing water to be drained from the solar farm system and ensure no water remains on the gate shortly after hibernation >

    Pool chlorinators can damage the pool heater or filter if they are obviously installed too close to other accessories. A check valve may be placed directly upstream of the built-in chlorinator, or possibly directly upstream of the flash point of a stand-alone chlorinator, to prevent high concentrations of chlorine from entering the heater, filter, or other nearby equipment.

    Remember that water will seek itself out when it is actually level, and if the hot tub, water feature, or water feature is placed at a higher level,than damaged water, they will naturally gravitate (in the pool) in suspension when the filtration is turned off. Check valves are used in spa return lines, hot spas and/or overflow lines to prevent loss of gravity in schools connected to common systems when the pump is turned off. Check valves can be used in the same way. B. for wall fountains, deck planes and waterfalls to prevent leaks when not in use.

    Spa Blower

    For pools with adjoining hot tubs, a vent duct is often attached to direct air into the plane of the hot tub. Many builders place the fan on a tall pipe, a few feet above the level of the pump, to prevent water from entering the fan motor. For added security, companies can usually install a check valve on the fan hose to keep water out of the motor fan.


    Ozonizers first use small ball check valves at the inlet to the specialAn ozone tube that delivers ozone gas to an injection unit (another type of small ball check valve). Manufacturers recommend replacing the ozone tube and test device regularly to ensure that the gas only flows in one direction and that water does not flow back into our own ozone production chamber.

    What happens if a check valve is stuck open?

    If that particular check valve is stuck in the open position, that particular pump will only work and pump at high quality; However, it does not protect against backwaters or floods.
