I think the only thing that causes water to shoot back is when air has been pulled into the filtration system. This usually happens on the suction side, between the skimmer and the pump. The air will accumulate in the top of the filter. It is subject to the same amount of pressure as the water in the system, but air will compress and store the pressure, like in an air tank. When the pump is turned off the air expands back to it's original volume, pushing out the water in the tubes connected to the filter. But an 8 foot spray sounds like a lot of pressure! Check the pump basket lid seal/o-ring for leakage. Watch it when you switch off the pump. If the water in the basket disappears, the problem is air in the filter. With the pump running, check to be sure the hose from the skimmer is not collapsing. Also if there is a tube on the return side of the system that is not in use and is capped at the pool, it may be filled with air and storing the pressure. I can't think of anything else. Good luck. One other thing. After you replaced the sand in the filter, did you run the pump with the valve in the backwash position for about 2 minutes to purge the air from the filter?
Empty the skimmer baskets and the basket that's attached to the pump. Then backwash and rinse the filter.
If you have the regular set up that includes a skimmer, pump and filter then you don't have to waste any water. Get an lid-to-hose adapter, that fits over the skimmer basket at your pool supply store. Fill the hose with water and attach it to the lid. Place the lid inside the skimmer over the skimmer basket, then vacuum to your hearts content. Pool Masters
Never put any chemical in your skimmer basket. It's not there for that purpose and can be harmful to the filtration system.
If bugs are'nt filtering out of your pool and you have a filter, obviously your filter is'nt working. Hope this helped. Bugs will naturally swim away from a strong current that is drawing them to a certain point. If the bug is not drawn into either the skimmer or the main drain grate they will never get to the filter. Even then, they will get caught in the skimmer basket or the pump basket. The filter is not intended for catching the bugs - that is what leaf skimmers are for. If thebug is on the bottom of the pool you can then vac it up but still it will only go as far as the pump basket.
Your skimmer door is called a weir. A weir is a pivoting flap, door or dam in a skimmer that keeps bugs and leaves from re-entering a pool or spa by collecting the debris in a basket while letting water recycle through the filter system.
Starting at the pool first is the static skimmer then the leaf basket then the hair filter basket on the inflow side of the pump then the pipe from the pump to the filter then the pipe from the filter to the pool return The chlorinator sits on the pool return pie at the highest place in the system.
There is air in the system and it is "burping". I usec to have the problem and I hard lined it from the pump to the filter. Also use teflon tape on any threaded connections. Make them tight but dont break the plastic. Also make sure your hose clamps are tight on the skimmer and return.
I clean my filter and skimmer basket and leave my pump running. I do not cover my pool. I guess it could depend on the weather in your area and if you have a problem with leaves getting in your pool.
Empty the pump basket of debris. When was the last time that you cleaned the filter? If after cleaning the filter it still does not work then contact me on my Message Board for further details. kbattle39 k
Depends on the use, more than likely once every few years.
The pool skimmer is the part of the system that the water overflows into for the pump to pump it thru the filter and other accessories. There is usually a screen or mesh basket to catch large debris before it enters the pump. On above ground pools it will be found hanging on the outside of the pool near the top. In-ground pools can have the skimmer placed anywhere along the perimeter with a basket or screen accessible for cleaning.
the skimmer that is normally fitted with the pool is designed to take care of this problem, however it rarely does because more often then not it is int he wrong place in the pool or the water is too high as the result of rain or leaving the hose in too long or the water is too low for the skimmer to work properly. If one ends up being the victim of one of the above problems chances are that a floating pool skimmer would be the answer to the problem. The type of skimmer you are looking for is a suction side pool cleaner that plugs onto the vacuum plate over the leaf basket. once it is set up to the particular rate of the pool pump it will rapidly remove a large percentage of debris dust and insects from the surface of the pool. Hum, the problem with the above answer is that once the skimmer basket if full and or the pump basket is full or any of the above solutions then what. Best bet is to use your telepole and a leaf skimmer that attaches to the pole ( you can also use a "leaf rake" or net as they are sometimes called. With this method you exert some labor and remove most of the leaves at one session.
