A multi valve pool filter is a common configuration of valve and filter for a swimming pool system. The piping into and out of the filter is attached to a multivale. A multivalve has has several positions. One type of multi valve has six positions:
backwash, waste, filter, closed, rinse and recirculate.
(These valve positions are used on a DE filter. A sand filter may be different.)
Use the filter setting in the nromal operation of your pool. This setting receives water from the pump and directs it to the dirty side of the filter media and then receives weater from the clean side and directs it to the pool.
Use the Backwash setting to flush the DE from the filter and to a drain.
Use the waste setting to flush water directly from the pump to the drain.
The closed position is, well, closed.
Rinse?
Recirculate?

What is the use of valve spring?
Valve springs keep valves firmly seated in the socket.
Which valve is prefered to use for ammonia tanks a globe valve or a gate valve?
If the purpose of the valve is to modulate flow, a globe valve is preferable. If the valve is only on-off, a gate valve is preferable because of lower pressure drop when the valve is open. As wikipedia , A globe valve is a type of valve used for regulating flow in a pipeline, consisting of a movable disk-type element and a stationary ring seat in a generally spherical body. So i think it is a globe valve to use in steam pipeline.

How come after you vacuum the pool clean about 2 hrs later bottom is dirty again?
Check that your filters valve is set to filter. The second thing to check is your spider gasket inside the multi-port valve (see below). If you have a sand filter that is more than ten years old, you may have to change out the sand due to tunnels that form with time through dirty sand. If you have a DE filter you may have a hole in one of the grids. The spider gasket in your valve may be deteriorated. Buy a spider gasket and some silicon grease at your pool store. Remove the screws in the multi-port valve and replace the spider gasket after you thoroughly cover it with grease. To keep this from happening again, never add chlorine through your skimmer. Always use a floater if you use tablets or install an off-line chlorinator as far away from the filter as possible. Hatawa
Why is your cartridge filter blowing debris back into the pool when sweeping?

What causes water to flow out of the pool filter backwash when pump is on and not on backflush?
Replace the spider gasket inside the filter valve. This is simple to do and should be done every couple of years, especially if you have an in-line chlorinator or if you add chlorine through your skimmer. Make sure you grease the gasket with silicon before you install it. To keep this from happening, make sure you have a check valve installed between the filter and the chlorinator or use a floater to chlorinate your pool.
Which swimming pool filter has the highest rating?
The best or highest rated swimming pool filter depends upon the use of the pool because a high use pool needs a higher quality filter. The most popular and therefore rated highest in the popularity sense are the Pleatco cartridges.
How do you clear sediment off pool floor?
You must have a vac system. Use it to remove the dust. The pool equipment can not do it all you have to help keep the pool clean by vac the pool, adding chemicals, cleaning the tile line etc. A pool is a money pit and labor intensive. You could also have a broken filter element with a D E filter. In that case get the filter repaired.
What will keep pool pump from sucking water from pool?
The pool pump does suck the water from the pool. Then it goes thru the filter and (if you use have the following) thru the heater and chlorinator then back into the pool. So - nothing will keep it from sucking water from the pool - but that's a good thing. Now - if you set the valve to a different setting - then it might actually send the water to a waste line - maybe that's what you meant. If that's the case -then the pool pump will eventually drain your whole pool if you have it set to get the water from the bottom drain (another valve).
How do i Get rid of algae in an empty pool?
Algae dust that comes from the algae fairy right? Anyway the best way to get rid of the algae skeletons (as one of my customers calls it) is to vacuum them directly out of the pool bypassing the filter. The problem is that these dead algae spores are too small for the filter to pick up so they end up going right through the filter. The best way to vacuum them out depends on what type of filter you have: SAND FILTER-Use the waste or drain position on the valve to vacuum your pool this will effectively remove the algae from the pool. You will have to refill the water you drain out of the pool when you are done. DO NOT COMPLETLEY DRAIN THE POOL. If the water gets to low stop and refill before you continue. D.E. FILTER-If you have a multiport (this valve will have at least 4 positions on it) valve on the filter put the valve in the waste position just like with the sand filter above. You will have to refill the water you drain out of the pool when you are done. DO NOT COMPLETLEY DRAIN THE POOL. If the water gets to low stop and refill before you continue. If you don't have a valve to backwash or you have a backwash valve that only allows you to filter or backwash then you have a difficult situation. The best thing to do is get an extra pump to use to vacuum the pool separate from the filter system. The other option is to plug all the return lines where the water comes back to the pool then remove the filter grids (if you have a grid filter) and open the drain valve on the filter and turn the pump on to vacuum the pool. Make sure that you have the water directed away from your filter system and your house. CARTRIDGE FILTER-Here you have a real problem if you have an in ground pool and about the only way you will get rid of the problem is to get a portable pump (or a separate pump) and vacuum the pool with this pump discharging the water out of the pool along with the algae dust. If you have an above ground pool you can plug the return and the skimmer. Then remove the filter cartridge from the filter. Reassemble the filter without the cartridge then where the water comes back into the pool take the hose connected to that fitting off the side of the wall of the pool and directed the hose away from the pool, filter system and your house. Then turn the pump on and vacuum the pool until the algae dust is gone. DO NOT COMPLETLEY DRAIN THE POOL. If the water gets to low stop and refill before you continue. FYI _ Cartridge filter they sell this bag that goes over your skimmer basket it cost like 8 dollars and it filters all of the algea into it so you dont have to drain the pool.
Can you use flock with a cartridge filter?
When you use flock you should not put it through the filter.When vacuming flock out of a pool with a sand filter you vacuum to waste. However you don't have that luxury with a cartridge filter. The ideal solution would be to put a 3 way valve between the pump and the filter and set it up so that one of the ports can be run to waste while at the same time shutting of the water to the filter.
What setting should you have your pool on for normal operation?
If you're talking about your pool filter, it should be set to filter or run. Use the bypass or recirculate setting if you wish to circulate the water without having the water pass through the filter. Use the backwash setting to clean the filter.
Can you use an in-ground filter on an above ground swimming pool?
Sure
Can you use chlorine in a pool without a filter?
Yes you can add liquid chlorine to a pool even if it's not circulating
What is meant when you say vacuum out to waste?
Some filter systems, especially sand filters, have a valve that allows you to exhaust the dirty water outside of the pool rather than return it back into the pool. For example, when cleaning their filter, many filter manufacturers instruct you to backflush to waste, meaning that you aren't supposed to return the dirty water to the pool but instead dispose of it outside the pool. Some other filter systems, like cartridges, do not always have this valve option. However, it is handy, regardless of which filter system you might have. There are always times when you might want to use your pump to dispose of some water (like when you're vacuuming out the really green guck on the bottom of a pool with algae). Hope this helps...
