How do you back flush a pool filter?
"BACKWASH" THEN RINSE THEN FILTER.K
Back wash valve when the pressure before the filter becomes to high usually indicated in red on the gauge the filter needs to be back washed.
The bypass valve in an oil filter allows the oil to bypass the filter if the filter becomes clogged. Some filters also have an anti-drain back valve when the filter is mounted in such a way as the oil could drain out of the filter. This valve prevents the oil from running back into the engine out of the filter which would cause the engine to be started with an empty filter every time.
Backwash valve is leaking by. More than likely it is a bad oring inside the valve. Or it was not place back into recirc mode completely. or you may have a leak on the return side of the filter. That includes all the plumbing from the filter or heater to the pool. The back wash valve may be obvious if the waste line ends close by. The back wash valve should be placed in the "filter" mode not the "recirculation" mode. K
Hmmm, do you possibly mean the back wash valve on the filter? This valve has many positions to choose from especially for sand filters. Filter, back wash, drain, drain to waste, filter bypass, closed. They are pretty much self explanatory. Normal position would be the "filter" position while the pump is running and the filter is working. Ken
Normal, you get a little blow back from the PCV valve system...
Possibly the filter did not have an anti-drain back valved installed. Purchase a name brand filter that has such a valve.
it is located on the engine (passenger side) in the back part of it you will see it if you take the oil filter and the idle valve it is attached to a little hose
There is a drain valve at the bottom of the radiator and you will have to remove the drain bolt in the engine block.
If you mean the cabin air filter, its under the hood, back up against the windshield on the passenger side. Its under a plastic cover - you have to remove a few plastic fasteners by depressing their centers and then pulling them out. Filter slides out. To reinstall fasteners first pull their centers out (above flush) and then, after they are inserted, push in the centers to original flush level.
I had the same thing happen after Jiffy Lube changed the air filter. They forgot to plug the vacuum line back into the back of the air filter housing.
This could possibly be that you are not running the back wash long enough or that there is a malfunction internally in the filter b/w valve. What brand filter? Ken
