DIGITEN 1/4" Automatic Shut-Off Valve with Quick-Connect Fittings For RO Reverse Osmosis

This replaced a part for my Watts Premier RO-PURE Plus system as the genuine distributor was out of stock. For half the price, this has been an excellent alternative. I installed it about 6 weeks ago, and it works as expected. I goofed and installed it with the colored tubes reversed, and I only noticed after it ran continuously for an hour, so I recommend snapping a quick photo of the original installation to remind yourself.

recently replaced my water filter system's valve with the DIGITEN 1/4" Automatic Shut-Off Valve, and I couldn't be more pleased with the ease of replacement and its performance. The installation process was straightforward, thanks to the quick-connect fittings that made it almost a plug-and-play experience. No leaks, no fuss. The valve automatically shuts off the water flow once the filter is full, which adds a layer of convenience and efficiency I didn't have before. It's a small upgrade that made a significant difference in the maintenance of my water filtration system. Highly recommend for anyone looking to simplify their water filter setup!

I replaced the old automatic shut-off valve because my RO system kept generating humming noise with different level of loudness. The water also taste not as pure as RO water. It seemed that all problems was caused by ripped membrane inside the valve.

I'm using this in a fairly simple float valve tank setup with regular 50-60 PSI water mains. If your shutoff valve vibrates and fails when installed with provided instructions, try this alternative installation instead.1) Connect the top IN to RO waste OUT.2) Connect the top OUT to your waste line.3) Connect bottom IN to RO filtered water OUT.4) Connect bottom OUT to your tank/reservoir.

Workes ask expected, simple to install. This was replacing a valve on a system not sold by this company. The old one has failed. This is working as expected. Good quality, the tubing grips in nicely, no leaks. So, result.

Didn't work very well, I was disappointed in all the replacement parts I received from Amazon on this particular project. They were cheap plastic and was not worth the time and effort to drain the reverse osmosis system and all. I would definitely buy it from a quality company that is going to get you good parts from the beginning

This worked fine for almost a year then is started honking worse than the one I replaced. Looks like I’ll try again with a different one.

My Watts Premier RO Pure Plus system was draining constantly and making a noise like angry bees. The water pressure at the spout was also low. I replaced all prefilters and the membrane and the post-filter to no avail. Tested with ball valve at the tank closed and discovered that the water kept draining. Replaced the original ASV with this valve (took ~10 mins with no tools) and the same test now passes. Fixed my issue and there is less noise when the water is filtering as well.
