Diverter valves are either two-way valves or three-way valves. Two-way valves let you control flow to and from one port. By rotating the handle through a 90° arc, a two-way valve can be turned off, on, or anywhere in between. Three-way valves are T shaped with one center port and two end ports.
How does a 3-way diverter valve work?
A 3-way ball valve works by turning the handle, which rotates a ball in the valve body, to align the cut-out channels in the ball with the inlets and outlets of the valve. The “L” shape cut-out of the ball on an L-port valve sends fluid through 90 degrees from one port to another.
How do pool 3-way valves work?
In effect a 3-way valve operates as a Tee fitting, with adjustable flow rates to or from each pipe attached to the valve. A simple pool may have one 3-way valve installed in front of the pump, to control the flow from the skimmer and main drain. … This results in 25% flow from the drain, and 75% flow from the skimmer.
What valves should be open on a pool?
A normal pool valve setting would have the skimmer valve(s) fully open, main drain half-open and spa drain fully closed.

3-Way Diverter valves are used to divert incoming water flow (from pump, etc.) applied at the INLET port to either of the different branches of the systems plumbing (filter, heater, solar collectors, skimmer, etc.). 2-Way Diverter and Check valves are used to block the flow of water in one direction only.
Should both holes in skimmer be open?
The skimmer sits at the waterline and catches leaves, bugs and trash so they do not clog the filter. Skimmers with a second hole help keep the pump from running dry if the water level is unstable.
Should pool return jets point up or down?

Do pool check valves restrict flow?One, check valves are prone to jamming in the open position, thereby becoming an uncheck valve of sorts. Two, they are prone to jamming in the closed position, preventing water flow in any direction. And three, they can restrict water flow.
Article first time published onDoes a check valve go before or after a pump?
The most common installation is at the pump. A check valve may be installed on the suction side of the pump to maintain the pump’s prime in the event of a pump shutdown. A check valve will be used commonly on the discharge of the pump to prevent backflow from the downstream system, when the pump shuts off.

Should pool skimmers be on all the time?

Where should a pool check valve be installed?
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 directly against the pump intake, but 12”-18” in front of the pump.
How do I stop the water flow to my pool pump?
There should be a valve in front of your pump that you can turn so that water can’t flow down to the pump while you have it open. Look for a ball valve or diverter valve that you can close.
Should pool main drain be open or closed?
For proper water circulation, it is best to position the flap so that it is about 2/3 closed. This will allow for more flow through the main drain than through the skimmer, which will promote a “bottom-to-top” circulation throughout the pool.
Do I need a skimmer diverter valve?
Skimmer diverter plates allow pool owners to determine where the water suctioned through the pool skimmer goes. The skimmer filters the pool water, helping keep your pool clean. … Diverter plates are necessary when you use a pool vacuum.
