How to replace filter sand


  1. Open air relief and drain plug to allow air into filter and water out.
  2. Take apart filter, remove all nuts/bolts/screws/fasteners and separate the filter. Could need some force to separate
  3. Use a shop vac to suck out the sand or a cup, be careful not to be too violent, if you damage laterals sand will go into the pool
  4. Check the laterals, No cracks or damage
  5. Close drain plug.
  6. Go to pool/home store buy POOL SAND. Amount required should should be posted on the filter somewhere. any extra will go into pool, or backwash out.
  7. Add some water about halfway of the filter, slowly add sand back into filter, dont be too violent. be careful not to get sand into any piping it will go back into pool.
  8. Prime the pump(add water to it) backwash the filter for 2~3 minutes
  9. Close air relief
  10. Run pump on normal open air relief as need to let excess air out .
Done!

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!

Pump is blowing cloudy water back into pool


Cloudy water is the bane of sand filters!. I suggest letting filter run day and night. Do not backwash until the pressure rises 8 - 10 pounds above clean starting pressure. Do not try to vacuum or stir up the sediment. when water clears, vacuum to waste. Keep the hose running while vacuuming. A dirty filter is a better filter (up to a point). At a higher pressure the filter will trap more of the fine particles that are clouding your water.

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.

After I vacuum the pool, backwash it and then turn the filter system back on it blows in a lot of green water back into the pool. What should I do?


1st Green water is algee. Kill the algee in the pool. 2nd when you're finished backwashing the filter. Stop pump and move valve handle to rinse position. Then restart pump. Run in rinse mode until glass is clear. Then stop pump again, and move lever to filter position. When you're backwashing, you're reversing the flow of the water through the filter. When you switch directly back to filter, anything left loose in the filter flows back to the pool. When you select rinse, it reverses the flow back to normal, but keeps the water going to the waste outlet until clear, that way that green puff of water will go out the drain. You can get complete manuals from www.haywardnet.com

How do i change the sand in the filter? I am getting sand in my pool.


You will simply remove the old sand from your pool filter and follow the instructions from your users manual like you are adding sand for the first time. In case you don't have it, I am going to paraphrase it for you below.

1. Be sure correct amount of filter sand media is in tank and
that all connections have been made and are secure.
IMPORTANT: To prevent unnecessary strain on piping system and valving, always shut off pump before switching Filter Control Valve positions.
The correct amout of sand can be determined with this link: http://www.backyardcitypools.com/pool-filters/Filter-Sand-Requirements.htm

2. Set your controls to the backwash position.

3. Prime and start pump according to pump instructions. (be sure all suction and return lines are open), allowing the filter tank to fill with water.

4. Once water flow is steady out the waste line, run the pump
for at least 2 minutes. This initial backwashing of the filter is recommended to remove any impurities or fine sand particles in the sand media.

5. Turn pump off and set valve to RINSE position. Start pump and operate until water in sight glass is clear—about 1/2 to 1 minute. Turn pump off, set valve to FILTER position and restart pump. Your filter is now operating in the normal filter mode, filtering particles from the pool water.

6. Adjust pool suction and return valves to achieve desired
flow. Check system and filter for water leaks and tighten connections, bolts, nuts, as required.

7. Set your filter to the "filter" position.

Are you using the rinse setting for a few seconds following the backwash? If not, once you finish washing, stop the pump, change the valce to rinse, then run it about 3 to 5 seconds. Shut down then switch to filter and the particles should stop coming back to the pool.
