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.
Stop the air compressor when the pool is inflated and the plastic is firm enough to resist medium pressure from your hand. Do not over-inflate the pool. Most air compressors will stop inflating when the pool is full of air. Others must be stopped manually (refer to your manual for details).
