I have a 2016 13' Scamp.  It has a hand pump for water.  I noticed there is a water pump under the front seat in trailer.  I would like to upgrade to a regular faucet.  Can I use the water pump already in trailer with along with a toggle switch to turn on the pump for water to the new sink faucet?   Any advise would be appreciated.

I just noticed this is for the power and not for the water supply.  Stupid!!  I am learning about RV's.   So my Scamp does not have an electrical powered water pump.  I assume the hand pump pulls the water from the tank by pushing on the pump with no electrical pump being used.   I will need to do some more research on adding a electric pump.
