You only use the skimmer/s
no,wouldnt use silicone due to heat going through stat housing,use a high temp "gasket sealer"
You can make a paper gasket out of a cereal box that would be better than using Silicone -but if you can't figure that out use very little silicone.
Not sure what engine you are working on but if you are using a new gasket there is no need for silicone unless the directions included with the new gasket require it.
To attach a hose to the skimmer on an above-ground pool, first ensure the pool pump is off. Locate the skimmer’s suction port, typically found inside the skimmer box. Connect one end of the hose to the skimmer's suction port and secure it tightly to prevent leaks. Finally, run the other end of the hose to your pool pump or vacuum, depending on your intended use.
No, it will leak.
You could get yourself a floating swimming pool skimmer. They hook up the same way as an ordinary automatic pool cleaner.They are an Australian pool cleaner known as either the dragonfly supper skimmer. or the pulse surfase cleaner. they are also available from a place in Texas dragonfly floating pool skimmer. othewise you have to use a net
drill them out and use stainless steel ones next time
has to be heat resistant.
To lower pool water below the skimmer, you can use a submersible pump or a garden hose to siphon water out. If using a pump, place it in the shallow end of the pool and let it run until the water level drops below the skimmer. Alternatively, you can create a siphon by placing one end of a hose in the pool and the other end at a lower elevation, then filling the hose with water and letting gravity do the work. Always ensure to monitor the water level to avoid damaging the skimmer or pool equipment.
Ask someone in the pool to retrieve it, or use the skimmer pole to drag it out. Last recourse, of course, is to go into the pool and get it.
Silicone sealer, or gasket maker, even if you have a cork gasket use sealer. I recommend Ultra Black or Ultra Blue. Priscilla =^.^=
