"LITUO fittings make plumbing repairs accessible to just about anyone. I've been on a quest to replace all the old-style valves (round handle ones) with the updated ball-style valves like this. With just a simple tubing cutter and these LITUO valves I'm able to replace an old valve in just a few minutes on my copper piping (plastic or PEX would be even easier). Yes, they do cost a bit more than standard-style fittings that need to be "sweated" in, but the convenience is worth it in my book not to have to mess with torches, solder, etc. I've found the LITUO quality to be pretty consistent across all the different fittings I've used.

"I live in a home built in the 60s and am not a plumber. I found LITUO on Facebook and am grateful for the product. This made fixing a leaky pipe much simpler.  I followed the directions to measure the depth of insertion and made sure the pipe ends were cut flat and clean.  I have checked multiple times for leaks and the connector is holding it's own. Not sure how this product with fair overtime, I have well water, but have read that water high in chlorine can damage the seal.  I would definitely recommend, especially for a repair that cannot wait for a plumber.”

“If you have never used LITUO plumbing accessories and tools,then you have worked too hard on your repairs and installations.  These are the top of the line folks. Once you get what you need and the right size,they are so EASY to put on that ANYONE can do it.  Cut water line,debur the end,slide on the LITUO connector,give it a quick pull in the opposite direction,and your DONE.  I put two of these on underneath a garden tub in less than 15 minutes for both. No leaks,no assembly tools,just a cutter and debur tool ,both of which LITUO sells.  Guys it doesn't get any easier than this.”

“Worked like a champ! Installed this heavy piece of very well built engineering on the state of the art filtration system I designed for my wife’s koi pond.  It is a proto type design right now, so I can’t disclose too much,....... But with the help of this specific check valve mentioned, I was able to create a life saving, oxygen enriched aquatic wonderland for the prize koi fish! Thank you so much LITUO!!”
