The model of pump doesn't really matter,You backwash the filter by changing the position of the backwash valve (while the pump is off). If you have a D.E. filter, be sure to add fresh D.E. powder to the filter when you are back in "filter" position.

Tip

Backwashing A Sand Filter with A Push/Pull Slide Valve or Multiport Valve


Lots of people are first time pool owners and pool professionals forget to teach these "newbies" about the simplest aspects of pool ownership.

One of the biggest questions we receive from new homeowners is "How do I go about backwashing my sand filter exactly?"

It doesn't matter if you have a Hayward, Pentair, Jandy, Sta-Rite or any other number of Sand Filters on the market they all utilize the same basic valves for backwashing; a push/pull slide valve or a multiport valve.


To backwash with a multiport valve:
1) Shut off pump motor.
2) Press down on valve handle, rotate valve from FILTER to BACKWASH position.
3) Roll out any backwash hose or open any waste line valves.
4) Open air bleeder assembly on filter, and turn pump on.
5) Watch pressure gauge for backpressure and hose for kinks. Be prepared to shut off pump quickly.
6) After hose fills with water, run for 3 - 5 minutes or until water runs clear.
7) Shut off pump motor and move multiport valve handle to RINSE position. Run on rinse for 15 - 25 seconds.
8) Shut off pump motor and move multiport valve handle to FILTER position.
9) Turn pump back on and note lower pressure.
10) Roll up backwash hose so the dogs use it as a chew toy.


To Backwash a sand filter with a slide valve:
1) Shut off pump motor, roll out backwash hose.
2) Twist to unlock plunger T-handle, push or pull(depending on manufaturer) the plunger 2" - 3".
3) Open air bleeder assembly on filter, and turn pump on.
4) Watch pressure gauge for backpressure and hose for kinks. Be prepared to shut off pump quickly.
5) After hose fills with water, run for 3 - 5 minutes or until water runs clear.
6) Shut off pump motor and push T-handle back down into locked position.
7) Turn pump back on and note lower pressure.
8) Roll up backwash hose.

Now you are a backwash Guru!

I need to know what all the settings are like bacwash filter on the valve system


FILTER is the valve position when the system is in the normal filtering mode.
When you backwash the filter you first need to turn off the pump, place in BACKWASH position, and run the motor for 45 seconds (or until the backwash water is clear). Turn off pump and run in the FILTER position for 15 seconds. Repeat twice more.
The RINSE position is to clear any dirt in initial start-up cleaning, plus resetting filter bed after backwashing.
The WASTE
position is for vacuuming directly to waste, lowering pool level, or draining the pool.
The CLOSED position is for shutting off all flow through the valve.
The RECIRCULATE position allows water to flow from the pump through the valve and directly to the pool.

You will probably only to use the FILTER, BACKWASH and maybe the RINSE valve position. The RINSE position is not as important as indicated by the fact that many backwash valves don't have a RINSE position.

I hope this helps.

Does this pump Dynamo DYN 11-n1-1 serial no 1-23-JO9 have to be backwashed and if so...how?


Pumps don't need to be backwashed, some filters do. Sand and DE filters need to be backwashed when the filter pressure has increased to 10 or 11 psi. depending on the manufacturers recommendation. The cartridge filter cannot be backwashed but instead it is removed and a hose sprayer is used to clean out the dirty outside. Your pump does need to be primed so it is not trying to pump mostly air. Each time the pump basket area is low in water then it needs to be primed. You will know how low it can go before it needs to be priming by turning it on when it is low and if it cannot start pumping water at full rate then at that level of water it needs to priming. If it is pumping water at full flow and you turn it off it should not need re-priming because there is enough water in it to force the air through the system. I hope this helps.

When cleaning pool filters that use cartridges, there is never going to be a backwash option. The cartridges can be cleaned and reused, but you have to take them out of the unit in order to clean them.

I find it interesting that you never had this problem. Did something change, specifically on the backwash of the iron filter? Is is possible that there is lower restriction to backwash causing the lower pump pressure? Could you throttle the backwash flow to allow pressure to be maintained and still get adequate backwashing?
It seems a lot of water must be flowing so that when you use some water the pressure drops to more than 10 psi below cut-in, that means typically 30 psi shutoff point.
Can you lower cut-in pressure, say 5 psi, lower?

De filter pressure too high water is cloudy


backwash the filter from main drain until sight glass is clear-this will reduce filter pressure. After backwashing return gate valve to filter position, then filter from main drain only. check water chemistry. add a clarifier to water

No water coming out when I backwash. I cleaned


water level must be about the discharge (eyeball) in the pool to back wash. Check the hose connections to make sure that hoses off the the filer head are going to the right place Look for the words "Pump" , "pool" and "waste" molded into the valve. I've seen it a number of times where "Pump" and "pool" were connected the wrong way.

Low water flow


1. If your filter hasn't been backwashed, that's a good place to start. 2. If you haven't done a seasonal disassembly and washout of your filter, that will allow a residual to build up and keep your flow low. 3. The control selector valve...you may want to open that up and make sure there's no blockage in there as well... only as a last resort. 4. Also, remove the basket in the pump and reach in to the intake port and check for debris...that'll do it too. Let me know if you get the pressure back up! K
