Mudder 6 Pack Float Ball Valve 1/4 Inch Adjustable Plastic Water Filter Float Valve for Ponds, Water Tank, Pump, Trough, Aquariums, Aquaculture, Reservoir

I'm writing this review because this is an incredible value, and I want these products to continue selling well. Many of the people are finding that these will not close correctly, or close at all. Some find that the float will not close until it is submerged by several inches. I also experienced this, and I figured out the issue. Since these are made of plastic, they will *slightly* deform if you overtighten the large nut. This imperciptible deformation causes the valve to stick, and may not close when the float is submerged. To fix this, fill the tank until the float is submerged, and then loosen the nut until the float pops up. You may hear the valve 'creak' as it closes. Try to loosen it a bit further as you manually open & close this valve until this creaking sound is eliminated. Don't loosen it so much that it leaks from the O ring. Also, like all plumbing, you will need to put teflon tape on the right angle adapter threads. All threaded plumbing threads leak without teflon tape. That said, these things are an INCREDIBLE value! They work extremely well, and they are incredibly inexpensive. I was worried that they might emit a cheap chemical smell, and I do not want any of that in my potable water application. They have no chemical smell at all, and they are well made :).

I've been using these for 2 Carolina Reaper pepper plants growing in hydroponic buckets. I have a central water reservoir that keeps the buckets topped up via these float valves, they've been in use for around 2 months now and I haven't had a single leak at all, they perform their job perfectly. I took the time to install them correctly, and they work. Additionally, I have 1 installed in the lid of a 5 gallon water bucket that I use to fill up my home and grow tent humidifiers with water from my reverse osmosis water filter system. I installed a t tap and valve into the RO system, so I can plug the float valve in the bucket lid into the RO system to have it fill the bucket for me, and have it shut off when the bucket is near full. In this situation, the valve shuts off a 95 PSI pump pressurised water line without issues. Average home water pressure varies between 30-80 PSI, so this valve is quite capable. Ignore the reviews that talk about the valve being normally open or normally closed and not working for people, the solution to their "problem" is to flip the thing around so the float goes the other way in the up and down direction, that is literally it. Those reviews are being posted by people who have no idea how water and gravity work.

These are nice when you don't have a lot of room to work with. I've put them inside 4" pvc poultry watering troughs. As long as the supply water doesn't have chunks of gunk in it, these'll work well for gravity feed systems. I've got floats that have been in continuous service for over three years and still working exactly as they should.

Perfect size for my project. Family forgets to fill ice maker. so no ice for cold drink when I get home from work. Installed in a counter top ice maker. Works great now ice is always full. Best of all impressed my wife . She thought I was crazy at first. But now she thinks I'm a genius. I really just saving myself from being aggravated after a long day.😊

I attached them to my o.r. system and to the fish tanks by drilling a hole in to the lids. Just be sure to install a shutoff valve so you can work on any adjustments easily. I leave the valve off when I not used so don't have to worry about leaks if something breaks when not supervised. So far I turn on the valve to fill all the tanks in about 20 mins at a time and no leaks. Be sure to use Teflon tape. Thanks for the great product for the price.

Was suppose to be a 4 pack, only 3 when it arrived and the package was not damaged

Using these for a hydroponic top off system from a central reservoir to totes. Use a 1/2 inch drill bit, bore hole is best. Teflon tape is a must, especially on the elbows. Works great so far, I can go away for a couple days now vs topping off myself every 12 hours.

They work
