Better screws!
Works perfect! Some reviews Complain about the heat molding but it looks just like the old one and I gave it a pretty good tug and it's just as strong as the other one. Didn't budge. Screws with this one are way better though because they give you Phillips head instead of the stupid flat head on the old screws. Phillips head is easier because the screw driver doesn't slip. No more leak! Ready for summer! Note: I have noticed this valve is notorious for breaking in winter. To blow the water completely out of this I hooked up my air compressor with the blow nozzle and disconnected the hose in the bathroom that connects directly to this valve and blew air in through that hose into the valve at about 20psi while holding the foot pedal down and it blew out quite a bit of water. We have cold temps approaching again. Hopefully this will keep it from freezing and breaking again.

I left a poor review previously. Maybe wrong on review.
It worked for about 1.5 years then started leaking again. After rethinking we had a wind storm at the park where we keep our 5th wheel. Power went out for two weeks in freezing temperatures. I blew the lines out prior to winter but doubt it would clear water from this valve. Leaking could be caused from freezing weather as there was no heat for 2 weeks. It worked great when reinstalled. Changing my review back to great.

1 bad one might be defective, 2 in a row means these are junk.
After my original valve cracked from freezing, I purchased two of these valves so I could replace and have a back up. After working for about 1-2 months the valve more and more wouldn't shut off properly. Until one day I had to have my GF stand there flushing the toilet every 10 seconds so it wouldn't flood the bathroom, while I shut the water off. It's was quite a nuisance (no more running water until it's fixed), but figured it wasn't a big deal. Probably just got a bad one. So I replaced it with my backup and all was well for 1-2 months. Then it started not shutting off again. It had to be slammed shut to stop the water flow. If you gently let off the pedal, it would run forever. So I ordered a different brand and replaced it. We'll see how that one holds up. But absolutely do not buy these. Now that I've had to buy 3 valves I haven't saved anything with this cheap replacement. And changing this out, although not complicated, getting to it is a nightmare. I'm also concerned about damaging the threads on the water line coming in. Every time I change it, I have to tighten more and more to make it not leak. So if I have to do this again I might have to redo the fitting on the waterline. They aren't made to be taken on and off over and over. They should be once every decade or so. The $30 saved is not worth the pain of having to change this repeatedly. Nor the anxiety of worrying if the water actually shut off. I'm sick of staring at the toilet for 20 seconds after every time I flush to make sure. And it definitely isn't worth the $30 if you miss it and take off for the day and find your camper flooded with toilet water. BUY ANOTHER BRAND! THERE IS NO SAVINGS HERE! Look at the other reviews, I'm not the only one with this problem. Sure some people didn't, but is this a good spot to roll the dice, considering what will happen if you get a dud.

Great product
Just like original. Easy to install. Two screws. Hard location to get into. Had to get a stubby screwdriver to install. Been working great!
