I'm asssuming your talking about the one on your skimmer basket. They swell with age to help keep a good seal. This means you have to replace them once in a while but that's better than a leak.
Pump the water out or put a cover over the pool.
To keep your swimming pool clean you will need a filters and a water pump. A vacuum would as be a good idea.
The pool pump does suck the water from the pool. Then it goes thru the filter and (if you use have the following) thru the heater and chlorinator then back into the pool. So - nothing will keep it from sucking water from the pool - but that's a good thing. Now - if you set the valve to a different setting - then it might actually send the water to a waste line - maybe that's what you meant. If that's the case -then the pool pump will eventually drain your whole pool if you have it set to get the water from the bottom drain (another valve).
Turning the pool pump off will help
yes, pool water clean chlorine make
You should run your pump about 12 hours each day to keep water clean. You can put your pump on a timer to save money. Don't do that until your water clean and clear. If you are still working to get your water just right you need to keep your pump going full time.
You will have to dig out underneath the pool and set a line underneath the bottom. You then attach this line to a pump. While you are building the pool you must keep this pump running.

NO POWER CORDS IN THEW POOL ! I KNOW ITS HARD TO KEEP THESE CLEAN SO THE BEST WAY IS TO FIND A INGROUND PUMP AND FILTER SAY A 1 HP STA RITE DURA GLAS AND A 50 SQ FOOT CARTRIDGE TYPE FILTER. WHEN THE POOL GOES BAD YOU WILL BE ABLE TO RESELL THE PUMP AND FILTER AND GET YOUR MONEY BACK..
A properly installed AUTOMOTIVE TYPE HOSE CLAMP would do the trick!
Quite possibly the drive belt is over tensionedANS 2 -You must tell us what kind of pump this is for a good answer. -Is it a water pump in an auto engine, a well supply pump, a pool pump ?
there is probably something in the pool that got into the pump
