Hyward Variflow valve lets water drain when in filter posi
When I backwash, rinse or set the valve to drain water from the pool then return it to filter, the water continues to flow out of the pool drain exit in the garden. It can be overcome by vigorously rotating the valve handle either side of the filter position a number of times then selecting filter. Is this a fixable problem? If so can a non-expert do it?

Re: Hyward Variflow valve lets water drain when in filter...
If you pull the six screws holding the valve top on and open it up. You will see what is called a spider gasket in the bottom of the valve and this is comming loose. If you pull this out and dry the valve. You will have old silicone in the grooves at the bottom. Carefully clean all this out. Take the old one to the store to match it up. Then put a thin layer of silicone on the new one and put in place. Reassemble and let sit for a few hours and you should be good to go.
In the future be shure the pump is off and all the presure is out of the system before you turn the valve. The water inside will resh over the gasket and pull it out of place causing this. So be careful. good luck.
Re: Hyward Variflow valve lets water drain when in filter...
The dude is right, However, you may not have to go to a pool store or get a new gasket. if the conditiion is in fair condition you can remove it lay it on a flat surface. then cover it with a heavy object to flatten it out try to be sure the shape is in the form it needs to be when you put it bback. btw. if your pool equipment is below the water level you may need to close a valve or two to keep pool from draining out while valve is open. you can even just shove paper towels inside the pipe to slow the water flo. the idea is to get the spider gaskett back in the grooves and in place. I have even used plumbers glue to do this while it is wet. just make sure there is no sitcky stuff of the top area of gasket or in valve body of filter valve. you can use alot of lube you may even want to use silicon spray to saturate all areas to help renew the elasticity of the plastic as it is probably from chemicals age and exposure. replace the valve parts like they were before and you may even want to add a ball valve on the part where the discharge comes out. you can just open it when you need to backwash or drain out water. this is a secondary safety device.

When the filter get clogged the pressure in the filter increases and there is less water flow returning to the pool. If your filter is a sand filter, when you turn the valve to backwash and turn on the pump it reverses the water flow in the sand filter to flush the dirt out of the filter to waste. Look at the window openning in the waste pipe and keep the backwashing goinging until you see clear water. Then turn off the pump and move the control valve to Rinse, turn on the pump for a few minutes, this returns the water flow back to normal but the water goes to waste to make sure the sand filter is clean. Turn off the pump and move the control valve to filter and turn on the pump. This mode is the normal operating mode and the pressure gauge in the sand filter will show a drop in pressure. Some pressure gauge shows a red section to indicate when backwashing should be carried out.
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.

during normal operation, your multiport valve should be in the "FILTER" position.
Once the pressure in the filter reaches 10psi more than what it was when the filter was clean, you should backwash. turn the pump off, press down and turn the multiport valve to backwash. turn the pump on and watch the effluent water until it goes from dirty to clean. Then place the multiport valve to the rinse position, this will rinse any remaining dirt from the top of the filter and valves so that it does not return to the pool. Once the water comes out clean, return the valve to the filter position.
Do not turn the valve while the pump is on, always make sure to turn the pump off before servicing any equipment.
Backwash until water in the sight glass is clear, shut off the pump and change the valve setting to rinse, turn the pump on for a couple seconds and then back off, change the valve setting to filter and return to normal operation. NEVER move the valve handle while the pump is on.
After your pool filters on the "backwash" setting, you should move it to the "rinse" setting. With the pump off, set valve to rinse. Start pump and operate for about 1/2 to 1 minute. This ensures that all dirty water from backwashing is rinsed out of the filter to waste, preventing possible return to the pool. Stop pump, set valve to "filter", and start pump for normal filtering. If it still won't start, check for restrictions in the intake and discharge lines.
Try these tips. I am guessing that one of these is the reason that your pool filter is not working properly. If you try these suggestions and they don't work, let me know and I will trouble shoot with you again.
1. Check skimmer and pump strainer baskets for debris.
2. Check for restrictions in intake and discharge lines.
3. Check for air leak in intake line (indicated by bubbles returning to pool.
4. Backwash your filter.
5. Be sure Vari-Flo valve is set on “Filter” position.
To Flush out the filter with the backwash setting.
The backwash setting releases trapped particles from the filter back into the swimming pool. You may need to alternate between the rinse and backwash settings until the water runs clear in order to unblock your filtration system and flush out clogs.
To Rinse away dislodged items from the backwash setting. The rinse setting flushes clean water through the pipes and carries away any particles or clogs freed during the backwashing.
To Drain the pool select waste on the multiport valve. This sends the water directly to the drain rather than back into the swimming pool.
Close the filtration equipment and stop the pump with the closed setting. You should only use the closed setting when you turn the pump off. This function allows you to remove the strainer basket, clean the filter tank and perform other swimming pool maintenance on the filtration system.
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
