Jandy diverter pool valves divert water and are available with two or three ports. A 2-port valve essentially acts as a 1-way-in / 1-way-out valve, allowing for water flow to be shut off completely or to restrict the flow of water for a lower flow rate.
How do you tell if a Jandy valve is open or closed?
On a two port Jandy valve, the valve has two closed positions and one open position. On the left, the valve is closed because the diverter is blocking the flow of water through the port. In the center, the diverter is blocking nothing, so the valve is open and water can flow through it.
How do you determine if a valve is open or closed?
Ball valves are perhaps the easiest valve to see if they are open or closed. If the handle on top is parallel to the valve, it’s open. Likewise, if the handle is perpendicular to the top, the valve is closed.
Should pool drain valve 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.
How do I know if my pool main drain is working?
you can tell if your main drain is working by perhaps putting a leaf on it. If it sticks, its working. In any case though, the main drain is not why your pool is having a problem. It has nothing to do with your pool turning green.
What position should my pool valves be set?
A normal pool valve setting would have the skimmer valve(s) fully open, main drain half-open and spa drain fully closed. To operate a suction pool cleaner or manually vacuum the pool, you can close other skimmers, or close the main drain, to obtain more suction through the skimmer you are using.
Should I Use main drain or skimmers?
Skimmer Vs. Drain. If the pool receives a lot of leaves and other debris, more suction may be required at the skimmer than the main drain to adequately strain debris floating on the surface. Conversely, if dirt on the bottom of the pool is the principal contaminant, more suction is required at the main drain.
Can you manually turn a Jandy valve actuator?
There are two (2) methods of manually rotating the JVA; one with power on (system operational) and one with power off (no power to the control system). 1. Move the toggle switch located on the bottom of the actuator to the opposite position (ON 1 switch to ON 2 or vice versa).
Should skimmer valve be open or closed?
For the cleaner to operate at maximum efficiency, only the skimmer and cleaner valves should be open. So it is either main drain+skimmer or cleaner+skimmer. Never main drain+skimmer+cleaner all open at the same time.
Does a pool need a backflow preventer?
Underground swimming pools also require a testable backflow preventer (PVB). To ensure water quality and for the protection of our customers, the BRWCD reserves the right to inspect all connections to our system for possible cross connections.
