sight glass
<img src=http://www.fiberglassrv.com/board/uploads/3e5a22ec3e793slight glass1.JPG/> Sight glass and a manual fill valve are stand along improvments the picture shows the sightglass using the plastic drain valves,the easy way for the sight glass is install 1/2" barbed tee in the tank drain line and one in the tank overflow line. Drill a 3/4" hole below level of the bottom of tank in the sink fiberglasss wall and the top 3/4" just above the level of water tank top,pull 10ft. of 1/2" polyurathane tubing thru the holes to the barbed fittings.job done,I think the addition of the plastic drain valves to hold the sight is more professional looking.would like to add a colored ball in the sightglass to be able to see :o the water level better .
