2 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 well.

I got these for a DIY koi pond filter. I frequently flush the filters and these float valves allow automatic refill. They have been in use for 3 or 4 months now with zero issue, so they seem to be good build quality.

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.
