In most residential swimming pools, the multiport valve is a most important piece of equipment, second only to the pool pump and filter itself. Most multiport valves have three main ports: The backwash valve, either a push pull or multiport valve attached to the filter, was introduced to switch the water direction in one easy movement.

Turn off the filter system. Backwashing with a multiport valve. Wait until it gets clear.

To access this gasket, remove the 6 to 8 screws on the valve cover. Turn the system back on and let it run for a minute or so. First of all, turn off the pump and the filtration system of the pool.

The main return port sending water back to the pool. This reverses the flow of water in the filter which flushes the dirt out of. Backwashing simply makes no sense given the way they are made and the way they work.

If you only have one return, use the filter's drain plug!) Set the value of the filter to backwash and check that the handle is locked. Connect the backwashing hose to the waste port;

If that is the case, there may be some debris stuck between the spider gasket and rotor of your multiport valve. Side mount multiport valves, for sand or de filters connect to the tank via two bulkhead flanges. Turn the filter system back on, and let it run for about two minutes.

As the backwash water leaves the tank, the dirty water is released out of the waste port of the valve , which may be. It is preferred by many because of its simplicity as well as its lower cost and better flow as compared with multiport valves. The push pull backwash valve (also known as plunger valve) is the most common valve in the pool industry.

Now fix the hose of the backwash with the water outlet. Restart the machine and let it run for about a minute. Turn the filtering system off;

Connect the backwash hose to the filter’s waste port. Backwashing a pool sand filter is a simple, straightforward process that involves switching the multiport valve setting of the pool sand filter to “backwash” then running the pump for a few minutes. Further, you will see it has a “backwashing” option, so turn it to that!

Again, turn the filter system off. This reverses the flow of water in the filter which flushes the dirt out of the sand and discharges it through the water outlet.this will allow pool water to flow out of the backwash valve or port.to do this, you should shut the pump off and push the handle completely down, then turn the multiport valve slightly to the right and the left, and back into the filter position. Screw this into the drain plug, clamp as long of a hose as you need to get the water somewhere you don't mind making mud, and plug your returns in the pool with 1.5 plugs (hint:

Very few installations add a valve to allow pumping to waste, bypassing the cartridge filter when vacuuming, so if you're not seeing anything like that, you likely don't have it. The waste port sends water elsewhere during vacuuming or backwashing operations. When the multiport valve is set to ‘backwash’ the flow of water through the filter is reversed so that all the dirt and debris that the filter has cleared from your pool water and has accumulated in the filter medium is then flushed out and sent to waste.

This will allow pool water to flow out of the backwash valve or port. A universal or side mount multiport valve needs five points of connection in order to function properly: Restart the filter machine and allow it to run for two minutes.

On the other hand, this is how you do it with a multiport valve. The valve is just that, a multiple porting valve for the water. Turn the multiport valve to backwash.

If you have a push/pull valve, open the backwash gate. The main intake port receiving water from the pump. However, you should not continue to see water come out of the waste port after you are done backwashing.

The pump, return, and waste ports. If this is so, you will need to flush out your multiport valve so the rotor can be. The port that feeds water to the filter intake.
