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.
For newly replastered pools (does not apply for pebble pools). Start up: Once the pool has started to fill, do not shut the water off for any reason. Wait until the pool is completely full. If you have concerns about overfilling the pool, turn the water down, do not turn if off. This will prevent a bathtub ring from forming on the plaster where the water stops.
