and if you or your parents dont have any water pressure. You can also get a pump like first one i posted. they make them in 12 volt and 110. With a on demand pressure switch built in. Just dont think they sell that type on this site. What you do is run one line in your water reserve. and another to your main plumbing. When ever you turn your water on pressure releases and pump kicks on auto. when you done with water it will auto shut off. if you in a rural area and worry about electric bills exc. You could always get a 12 volt solar panle and use a couple car batterys and get free electric . The type of pump im talking about is used in travle trailers. some places call them caravans.
