Re: installing new water system
22 gallons goes by real quick when you have an electric pump.
First, decide what you are going to use the water for, and make sure it lines up with how you intend to use the boat.
22 is fine for an extended weekend use, not for fresh water flush - and know how to take a 'navy' shower'.
A manual foot pump is the way to go on small systems. First clean the existing tank. Shock it with bleach, open the inspection port (install one if you need to - it's simple). Scrub it and flush it.
Silly to replace it, most folks are drinking water from systems more than 40 years old in their homes.
Rip out all the old hoses and fitting and install new marine rated fresh water hoses and fittings. Do not skimp here, the hose is important.
Get a foot pump - and on the pump to galley sink leg install a simple, home type, activated carbon filter. In the head, just a foot pump - you don't drink from there.
For faucets, most of the ones you see at home depot will work/fit. You'll want the kind that have a detachable head spray. Mind the material, rust is not your friend, but plastic does work.
I carry 130 gallons of water, we use a foot pump and filter as described above for all 'consumed' water.
For showers, get a solar shower and fill it from the sink. Lay it out in the sun for a couple hours for a nice hot shower. Note that a sun shower is also useful for rinsing dishes over the side, cleaning the cockpit, and even spraying down the deck with fresh water after a salt water rinse.
Lessons learned are opportunities earned.
