You’ve just bought that new house that was included with a swimmingpool. Since you check out the pool pumps and sand filters, you encounter the 6 position multiport valve and also no idea how it works. What do what filter, backwash, rinse, waste/drain, and closed mean?
The multiport valve, that can be known as an MPV mounts to either the bulkhead fittings on the side of the Sand or Diatomaceous Earth DE filter. Unlike both position push-pull valve that is filter or backwash, the multiport valve has six rankings and consequently six options. Always verify the pump is off before moving the valve into an alternative position.https://www.kplokusa.com
Since the water goes through the sand or Diatomaceous Earth particulates like sand, algae, sulfates, or carbonates will become trapped. The water is then going to be received through reunite pipes at the bottom of the sand filter. Clean filtered water is then going to be returned into the pool. As water moves through the filter medium and results in particulates, the filter will become more efficient in cleaning the water as smaller particulates become trapped. A disadvantage with this particular and every filter that accumulates particulates is that the filter pressure will increase, and also the pressure of the return water tends to decrease. When the filter is saturated in particulates and the pressure is extremely high, usually above 10psi it is time to clean out the filter.
Fixing a sand filter is significantly easier than cleaning a capsule filter. As cartridge filters have to be disassembled to be washed, a sand filter only has to reverse the flow of water to eliminate the particulates. In order to accomplish this, turn off the pump and then move the valve out of the FILTER position into the BACKWASH position. Once the valve has been securely set up at the BACKWASH position, just turn the pump on. Water will flow backwards through the filter and the particulates will undoubtedly be pumped out the drain onto the filter. The pump simply needs to be on for back wash for two to three minutes. Just see the sight glass and then watch as the water turns from brown or green color straight back to clean. Once this is accomplished, turn off the pump and move the valve into the RINSE position. RINSE will pump water through the filter throughout. However, instead of the water being pumped into the pool it will nonetheless walk out this drain. The purpose of RINSE will be to flush any residual particulates and assure once the valve has been returned to the FILTER location no particulates will return to the pool.
When whenever your swimming pool is full of algae soil that could simply move across the sand and be returned to the pool you are going to want to make use of the WASTE setting on your multiport valve when you vacuum cleaner. The WASTE setting bypasses the filter and drains all of the water into the drain. The only efficient way to inform if the WASTE setting is necessary is to watch the return jets on your pool since you vacuum the algae or dirt. If you find the problem vacuumed up being sprayed to a pool, it’s recommended to vacuum the swimming pool in the WASTE setting.
The re-circulate setting circulates the water, KP-Lok Automatic Recirculation Valve by passing the filter altogether. Most pool owners do this only once the water is really clear that they believe that it will not need to be filtered. A pool owner may also choose re-circulate if they possess algae and also have only shocked the pool. This setting is helpful to spread across the heavily chlorinated water afterwards shocking to kill the algae and vacuum it up after it dies and sinks to the ground.
The previous setting on the multiport valve is CLOSED. No water will enter or leave the filter container , or go back to the pool. Once the position is CLOSED, usually do not run the pump because damage may occur to the impellor.
