Why vacuum pool to waste

Let it run until it reaches its normal level. I also have an automatic top-up facility which keeps the pool at the correct lever, and you my have too, but it is much quicker to supplement this with a garden hose too.

So you just need to remove the vacuum head and vacuum hose from the pool, clear up and put the pump back on after putting the multiport valve back into the Filter position. When I first bought my house with a swimming pool I knew nothing about how to clean and maintain it. I normally check the chemical levels at this stage and add anything necessary to bring the levels to the correct reading.

It is often not possible to remove all all the dirt from the bottom since you need to vacuum so quickly. Also, it is inevitable that while vacuuming quickly to waste that some of the finer dirt particles will have been disturbed and will be floating around the water in suspension.

I therefore let the swimming pool settle down for 24 hours, allowing all the finer dirt to resettle on the bottom, and I then give the pool a thorough vacuum on the filter setting.

When you select waste on the multiport valve , and run the pool pump, the water does not go through the pool filter, nor does it return to the pool via the pool return. This way the dirt that is picked up by the vacuum does not get trapped in the filter, clogging the filter medium or even returning to the swimming pool, but is ejected from the system completely.

As the water does not go back into the swimming pool the water level will go down as you vacuum, actually at quite an alarming rate, particularly if you have a relatively small pool.

It is then that you appreciate just how much water your pool pump actually moves. You will have to top the pool up afterwards. Since the water containing the dirt does not pass through the filter if vacuuming a pool to waste there would normally be no need to backwash afterwards. If the pressure is high then you may wish to backwash to reduce it and improve suction. There sometimes no waste setting on a cartridge filter, at least in a Hayward system, so you cannot filter to waste.

However it is possible to fit a Hayward 3 way valve to bypass the filter and if you do that you will then have the facility to vacuum to waste. Some cartridge filters have a drain plug on the back of the filter housing which you can unscrew.

Pac-Fab push-pull valves have a reverse operation, up for Filter, down for Backwash. For DE filters , you can remove the grid assembly and reassemble the filter tank tightly, being sure that the clamp is properly positioned and very tight.

Open the air bleeder and set the push pull in the backwash position. Adjust your skimmer and main drain valves for maximum suction through the skimmer, and voila!

If the push pull plunger falls down, into the filter position, use vice-grips or a small wrench to hold it in place. It would seem that there is no way to vacuum to waste a sand filter — or is there? There is a method, but it can be dangerous, so read carefully. Remove the plunger from the slide valve housing or body by loosening the large union nut, small bolts or nuts on the top, under the handle.

Clean off any lubricant inside the valve body. Then insert a rubber expansion plug, usually a 11 or 12 , down into the valve body. This setting is useful for vacuuming the pool and sending large amounts of dirt, organic pollutants such as algae as well as certain chemical pool treatments directly down the drain so they do not contaminate or overload the filter media. Close the pool main drain valve and the valves leading to any skimmers other than the one you will utilize for the pool vacuum source.

Mate the extension pole with the vacuum head, and attach one end of the vacuum hose to the end of the extension pole. Place the vacuum head into the pool at the deep end, and hold on to the extension pole to stabilize the vacuum head as it sinks to the bottom of the pool.

Submerge the open end of the vacuum hose to flood the hose with water, pulling the remainder of the hose into the pool as it fills with water and sinks. This is quick and easy to do. Simply attach the vacuum head to your telescoping pole remember, it should snap on easily. Attach one end of the hose to the vacuum head and attach the other end to your skimmer using the vacuum plate. Remember to take the skimmer basket off first!

To keep your pool properly filled, use a garden hose to ensure a steady stream of fresh water and keep your water level even. Move the vacuum like you would a real vacuum on a rug, in slow linear passes going too fast will just stir up the dirt without sucking it up. If the pool is especially dirty, you may have to stop and empty the pump strainer before continuing. Repeat the process as many times as you need to remove all debris from the floor of your pool.
