I have put my hayward 710 multiport valve assembly back together and need to figure out how to put the handle back on. The handle has a pin assembly and does not seem to fit once everything is assembled. What is the trick to get the handle on?

Place valve on ground, sit in chair and place feet on top of valve. Press down evenly and the spring will compress. Insert pin in one side of handle then tap in lightly with hammer until even.

Water is leaking from filter control valve when system on and it sounds like seal may have been broken? Where should I look to fix.?


That sounds like the multiport. You need to make sure all the gaskets inside are in good shape and that all the screws holding the multiport together are tight. First start by taking the lid and handle off of the multiport, there is a lid gasket that may be in bad shape. If the gasket leaves black on your fingers, then that says the gasket is bad. Replace it and tighten the lid back down with the screws and bolts.

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 replaced a spider gasket on my PAC FAB 2# Multiport valve and when I put it back together the sequence is off. Filter mark is actually the waste port and waste is actually the Filter port.... how do you...


There should be a screw hole in the valve lid that has a flat edge on one side (outside edge). The valve body has a matching flat edge that aligns with it.
In the event the handle was removed from the lid and diverter to replace the diverter o-rings it is not uncommon for people to put the handle back on the diverter 180 degrees of where it should be. The pointer on the handle should be aligned above the open port of the diverter. This is true of all multiport valves except the Hayward four way valve.

Changed sand now the multiport valve is leaking at very top?


Is it leaking at the joint between the tank and valve, between the two halves of the valve, or from the center of the valve (around the handle)? If It's either of the first two, you may need to replace the o-ring. Take it apart, and check to make sure the o-ring is in good shape, and seated properly. If the o-ring is flat, oblong, or leaving black on your hands, then you should replace it. If it is leaking around the center of the handle, then you need to replace the o-ring and/or teflon seal on the shaft of the stem assembly (the part the handle connects to. To get to this you need remove the top half the valve, then drive out the pin that holds the handle on. (make a not with direction the handle and the stem are. otherwise you can be 180 degrees of when you put it back together. Hope this helps. If you need further assistance post a reply in the comments, and don't hesitate to leave a good thumb rating if you found this helpful. Thanks, and good Luck!

Hayward S180t filter w/ hayward sp 711 multiport valve. I removed to multiport valve to fix the spider gasket. I didn't think to mark so I could put the multiport valve back on. I need to know how to put...


Hayward 711A13 Vari flow valve. When I push down the handle to move valve into other settings the handle does not want to relock into the next setting. I have to manually pull up un the back of the handle and tap with my hand to get spring to retract. What can I do to lubricate this sping inside?

I need to change the lateral holder assembly and bottom screen on a Hayward S-200 sand filter. Will I need to remove the variflow valve or will it just come right out?


You will need to remove multiport valve and remove all the sand with a scoop. Not alot of fun. Think about replacing sand with ZeoBrite filter medium when you put it back together
