Hi,
I have an older DVK-6 multiport valve. There are two positions which I am not sure of…Whirlpool and Test.
I am gonna guess Whirlpool is just recirculate without involvement of sand…not sure about test setting. Can you please enlighten me?
Thanks!
Hi mbedpool,
Below are the descriptions for each of the settings on your DVK-6 Valve.
1. FILTER gives a downward flow through the filter bed. Dirt accumulates in the sand as filtering proceeds, and gradually restricts the flow of water until backwashing is necessary. This position can also be used for vacuuming.
2. BACKWASH gives an upward flow through the filter bed that removes the dirt from the sand and carries it to the waste.
3. DRAIN is for pumping water from the pool. It allows the flow from the pump to bypass the filter and go directly to the waste. You can also use this position to vacuum heavy concentrations of debris.
4. WHIRLPOOL bypasses the filter to obtain the optimum performance from a hydro-air fitting fed by the filter pump. (No filtration occurs in this position).
5. WINTERIZE allows air to leave or enter the tank to help priming and draining. Only to be used when pump is off. 6. RINSE gives a downward flow that settles the filter bed after backwashing and carries any remaining loose dirt to the waste.
6. RINSE gives a downward flow that settles the filter bed after backwashing and carries any remaining loose dirt to the waste.
7. TEST prevents only backflow of water from pool during pump maintenance if filter is below water level
I hope this helps
Thank You
