6 Pack Float Ball Valve, 1/2 Inch NPT Thread, OD. 0.84 inch (21.34mm), not 1/2 inch, Adjustable Arm for Livestock Water Trough, Aquariums, Hydroponics - Automatic Fill and Control Water Level

Good product

I use these as auto levelers for my koi pond. They don’t “flow” water. It’s more of a gentle spray, which I like; I think it makes it much easier to manage too and less likely to break.

Work great

Works very well and was delivered as promised

excelente producto

I'm using 1/2 drip line with 30psi drip to fill my watering bucket. The valve never fully shuts.

Worked great in my homemade chicken waterer.

I needed to replace the float valve in my 41" Swamp Cooler, 4800 CFM Evaporative Air Cooler with 10.6 Gallon Water Tank, Portable Outdoor Air Conditioner and picked this float because it looked like the plastic was stronger and the threads seemed deeper than the original float that came with my cooler. This float was very east to put in my cooler and I was happy to find that the plastic is much stronger and the treads were in fact deeper so they will not strip as easily. I'm very happy with this purchase.

These worked well, I use them for hydroponics, to set the level for Kratky system. Note the float valve should be in an auxillary bucket or resovoir to the buckets with plants; otherwise plant growth will interfere with the valve.

Very happy

Merveilleux le bonheur... manque jamais d'eau et toujours fraîche wow liberté facile à installé

The one unit tested wouldn't fully shut off

J'ai installé cette valve sur un réservoir d'eau alimentant une pompe et un chauffe eau instantané. Efficace et très facile à installé. La valve ferme l'arrivée dès que le réservoir est rempli au niveau désiré.
