How far should a check valve be from a pump?
In submersible pump applications, the first check valve should be installed directly on the discharge head of the pump or maximum one pipe length (20 feet) above pump. Water pumped and flowing through a piping system has a certain amount of energy (weight x velocity).

How to keep solar water from draining?
Check valves in solar pool heaters help keep the solar system from draining down once the pump turns off. You could also put another valve on the pipe that returns from the system. Placing one here will prevent the water from going back through the panels after the system is turned off.
Why use a swing check valve?
While spring check valves can be used in pools and spas, many people prefer to use swing check valves. There are two reasons for this: 1 Swing check valves don’t clog very easily when compared with the other styles of check valves. 2 The springs on a spring check valve can be prone to easily deteriorate, especially when they’re exposed to severe conditions.
What is check valve strength?
Check valve strength is another thing to consider. For example, different spring valves come in different strengths. Most valves have springs that allow for reasonably light resistance; however, you’ll probably want to opt for something more substantial if you require more strength. This is especially the case when you have increased pressure on backflow, which is often the case with solar panels installed on a roof.
Why don't swing valves clog?
There are two reasons for this: Swing check valves don’t clog very easily when compared with the other styles of check valves. The springs on a spring check valve can be prone to easily deteriorate, especially when they’re exposed to severe conditions.
What type of valve is used in a pool?
Ball Check Valves. The final type of pool check valve is ball check valves. While they’re not used as often as the other two types of valves, they are often used in chlorinators or ozonators—anywhere where you might need a smaller-type check valve.
What is a spring flapper valve?
With a spring flapper check valve, there is a flap on one of the valve ends. This flap pivots against a spring once the water starts coming out of the pump. The flap then releases downward, which closes any flow that would reverse course after turning the pump off.
Why do we need a check valve?
Check valves can be used in order to avoid gravity draining of water in the filter, pump, and pipes when a pool’s pump shuts off. They also keep raised spas, fountains, or solar heaters full ...
What are the different types of check valves?
In regards to internal operation, there are three basic types, swing check valves, spring check valves and ball check valves. Swing check valves have a flapper door or diverter on a hinge that swings closed when the pump is off, and swings open, in one direction only, when the pump is on and pushing water through the valve. Ball check valves utilize a round ball inside that rolls closed when not under pressure, and rolls open with the water flow.
What is a check valve on a pool heater?
A check valve placed on the pipe that leads to the solar panels will prevent drain down of the solar system, when the pump shuts off. A second check valve may be placed on the pipe that returns from the solar system, ...
Why do you put a check valve on a pool?
For pools that winterize their system during winter, placing check valves on vertical suction lines prevents air from being blown backwards through the skimmer and main drain pipes. There also is the concern of water being trapped on top of a vertically mounted check valve.
What is a spa overflow line?
For pools with attached spas with a controller, a spa overflow line or spa make-up line (bypass line) is often used to send enough filtered water to the spa returns to keep it clean and circulated, as the spa drain and spa return valves are normally closed. When the valves are opened to Spa Mode, a check valve is used on the spa over-flow line to keep water from looping backwards through the overflow pipe.
What is an ozonator?
Ozonators. Ozonators use small ball check valves on the ozone feed tube that carries the ozone gas to the injection fitting (another type of small ball check valve). Manufacturers recommend regular replacement of the ozone tubing and check valve, to keep the gas flowing in one direction only, and to prevent water from backing into ...
What is a check valve?
A check valve is a one-way flow valve, with a purpose to keep water from flowing backwards or to prevent cycling of water in solar systems or bypass loops. Check valves are used in pool, spa and fountain plumbing to keep water flowing in only one direction.
Where is the check valve located on a pump?
As such, a common location for a check valve is on the incoming suction pipe, in front of the filter pump. For best results with pump priming, especially for pumps lifting more than 24” from the water surface, the check valve should not be installed ...

The 3-way diverter valve can be open and closed stop water completely, allow water through 1 of the 2 outlets, or allow water through both outlets.
Why are butterfly valves called butterfly valves?
The technical term for these are Butterfly valves because they can flap open and closed. No, there’s not a lepidopterarium (it’s a real word) or butterfly sanctuary, in the valve. Think of it as a big flap. When it’s closed, the flap completely blocks the pipe and stops all the water flow.
What is flocculant used for?
When using a flocculant, of course. Flocculants are used to clear cloudy pool water and need to be moved around your pool without being filtered out. If all of those functions weren’t enough, multiport valves actually have a winter setting too!
Why do you need a check valve in a pool?
Check valves, also known as non-return or one-way valves are installed in plumbing to prevent the backflow of water, usually due to gravity. Also, if the pump is turned off, there’s nothing to keep the water from flowing the wrong way. This could lead to some nasty situations ending up in your pool.
How does a solar pool heater work?
Solar pool heaters work by warming the pool water in the toasty rays of the sun, usually positioned on your roof for optimum coverage. When your pump is turned off, though, all of that water is just going to go splashing back down thanks to the laws of physics.
What is automatic chlorine?
These devices chlorinate your pool as the last stop the water makes as it moves through your filtration and circulation system, pumping super-concentrated chlorine into the water at the last second to sanitize your pool.
