ump ▁off ▁all ▁together : ▁This ▁is ▁when ▁a ▁combination ▁of ▁a ▁slow - act ing ▁ins ul in ▁and ▁the ▁p ump ▁bas al ▁rate ▁work ▁well ▁together . ▁The ▁p ump ▁can ▁be ▁removed ▁before ▁a ▁pre pl anned ▁activity ▁( any thing ▁from ▁football ▁practice ▁to ▁water ▁ski ing ▁to ▁dan cing ), ▁and ▁the ▁p ump ▁user ▁continues ▁with ▁the ▁reduced ▁bas al ▁ins ul in ▁coming ▁from ▁inject ed ▁L ant us ▁or ▁Lev em ir . ▁After ▁the ▁activity ▁is ▁complete , ▁the ▁p ump ▁goes ▁back ▁on . ▁ ▁Water ▁activities ▁While ▁most ▁ins ul in ▁p umps ▁are ▁water proof ▁( at ▁least ▁when ▁they ▁are ▁new ), ▁the ▁high ▁cost ▁of ▁the ▁p ump ▁often ▁leads ▁to ▁ca ution ▁on ▁the ▁part ▁of ▁the ▁user , ▁who ▁often ▁removes ▁the ▁p ump ▁when ▁planning ▁to ▁get ▁wet . ▁Additionally ▁most ▁p ump ▁manufact ur ers ▁recommend ▁that ▁the ▁p ump ▁be ▁removed ▁even ▁if ▁it ▁is ▁water proof ▁as ▁water proof ing ▁is ▁only ▁guaranteed ▁ide ally ▁and ▁cannot ▁take ▁into ▁account ▁wear ▁and ▁te ar . ▁However ▁water proof ▁p ump ▁cases ▁for ▁water ▁sports ▁are ▁available . ▁ ▁The ▁p umps ▁can ▁always ▁be ▁dis connected ▁for ▁short ▁periods ▁for ▁bath ing ▁with ▁little ▁issue . ▁However , ▁for ▁parties ▁in ▁a ▁hot ▁tub ▁or ▁for ▁a ▁day ▁at ▁the ▁beach , ▁removing ▁the ▁p ump ▁and ▁" going ▁un t ether ed " ▁can ▁be ▁a ▁welcome ▁vac ation . ▁
