ISTR Lowes or Home Depot selling a nifty little kit you attach to
your
water hose to do just that. It had everything you needed, for a
decent price I recall, although it assumed you were a homeowner from
the design. It's been awhile, and I couldn't find it on either of
their web sites.



Stanley makes a water level that comes complete with clear tubing.
