Why vaccinate adults against hepatitis B? Hepatitis B can lead to cirrhosis, liver cancer and death. Hepatitis B is incurable. Up to 1.4 million Americans have chronic HBV infection. Hepatitis B is 50 to 100 times more infectious than HIV.
Re: Pool about to overflow from heavy rain dunno of this works, but try this: put one end of a hose in the pool, the other in a lower part of the garden. Now you need to suck on the hose (the side outside the pool) untill water starts running, normaly, the water will drain.
Put enough water in the bathtub or sink to cover the bottom of the plunger, block the overflow outlet with a rag, put the plunger over the drain, and push down and up five or six times. The pressure should clear any clog and open up the pipe. Lift up the plunger and the water should quickly drain away.
