Tank Fill Valve – the water level looks after itself

The float drops with the water, the valve opens, and it closes again once the level is back where you set it. It suits rain barrels, holding tanks, garden ponds and solar cylinders. The body is 304 stainless steel with a 201 stainless float.

Why choose this fill valve?

Watching a tank by eye works every week except the one you are away. A float valve does that job continuously and never forgets a day. Stainless steel handles a full season submerged without corroding.

• Automatic cutoff: the flow stops the moment the float reaches its level.
• Stainless build: a 304 body and a 201 float, both made for standing water.
• Small envelope: goes into narrow containers and tight openings.
• Inlet options: top-feed or side-feed, whichever suits the pipe you have.
• Hand fitting: threads into most standard openings without tools.

One fitting that quietly takes a recurring chore off the list.

Mount it so the float has clear travel and never touches the tank wall. Choose the overhead version if the line comes down into the tank, and the side version if the line arrives through the wall. Once a season, look for grit around the hinge.
