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.
Turn OFF the pool pump. Turn pool control handle to backwash. Turn ON the pool pump. Watch for the dirty water to flow until it becomes clear. (Most filters have a clear bubble on the side that allows you to see the water as it flows out of the system) Turn OFF the pool pump. turn the handle to rinse.
