Chem-Tainer 3/4 Inch Water Tank Float Valve (VALVE ONLY)

The 3/4 Inch Water Tank Float Valve (SKU FK0075PO) is the mechanical shutoff that keeps a water tank from overfilling. Chemtainer builds it from PVC with a 3/4-inch threaded connection: it threads into your tank's fill line and closes automatically as the water level rises against the float, then reopens as the level draws down. It is sold as the valve only, so before you order, confirm the components included and verify that the assembly you already run is a 3/4-inch match.

Does it work for my tank?

This is a compact part with an exact envelope of 7 in long by 3 in wide by 3 in high, a 3/4-inch inlet connection, and an empty weight near 1 pound. Match that 3/4-inch thread to your tank bulkhead or fill fitting, and size the float travel to your tank's usable depth. Note that it ships without a bulkhead fitting or gasket, so you source the tank-wall seal separately. If you are still specifying the tank itself, the Tank Sizing Calculator and Tank Sizing Guide help you land the right capacity before you add the fill hardware. See the technical drawing on this page for the connection geometry and the 7 by 3 by 3 in envelope.

Water service only

Because it is PVC rather than metal, this valve is intended for water service, not chemical duty. The part carries no chemical certification, no specific-gravity rating, and no elevated-temperature rating in its published data, so specify it for ambient potable or process water only. An aggressive chemistry needs a valve and tank matched to that duty, not a PVC float valve borrowed from a water fill line.

How it ships

This valve is a small, light item that ships from the nearest stocking location. Chemtainer water hardware stocks from several regional points, including Lancaster, OH and West Babylon, NY, along with Texas, Florida, Hawaii, and Pennsylvania stock, so most buyers draw from a point within a region or two. If you are ordering it alongside a full tank, freight is quoted live to your ZIP and the valve rides with that order. Run your delivery ZIP through the Freight Cost Estimator for a live number, or call 866-418-1777 and we will confirm the closest ship-from point and combine it with any tank on the same order.

The mistake to avoid

Do not press a PVC float valve into chemical service, and do not assume the 3/4-inch size fits sight-unseen. Confirm the 3/4-inch thread against your existing fill line before you buy, since a float valve that does not thread cleanly to your bulkhead will not seat or seal. For water applications, a correctly sized 3/4-inch float valve is the simplest way to keep a tank from overflowing.
