Made very well
Fit like a glove. Does not come with the butyl tape to seal it to the camper exterior but a quick trip to the home store fixed that. Easy installation with no leaks.

Everything went well
Everything went well for me. I carefully installed and took my time. No leaks of any sort. It is still holding and working 2 years later. The old one went bad and I needed this new one. Thankful to have saved some money and do it myself.

This was a good value
they did not give you a option for a 45 deg. for hookup in motor home Home Depot has what you need if a 45 is needed. other than that it was easy to install and works great I would buy it again if I needed one. The backflow preventer is much better quality then what the RV manuf. install it is all brass not cheap plastic.

Good Overall Quality
I used this hookup to replace an old rusty one on my 1990 Winnebago Warrior. After shopping around, this water-fill seemed like the highest quality option out there, with brass plumbing all the way through. The product fit well but the plastic mounting flange (which seems pretty thick) was not very rigid, so I watched the assembly flex as I attached my PEX on the inside of the camper. After a full month and 9,000 miles on the road, I'm happy with the purchase and expect it to last as long as I own the camper.

This is the one you're looking for!
Foolproof, faultless. It's US-made, quiet, and seals perfectly. I bought it to replace a Chinese mfg inlet whose steel dish began for rust almost from the first day of installation, leaked and was noisy (check valve poorly calibrated or designed) regardless of the water pressure.. Do yourself a favor--spend a few more dollars and get this original quality OEM item.

Perfect replacement. For the size used on my RV. The original froze and the check valve was stuck shut. Easy install.

Great check valve!!
Check valve on city water connection went out on our RV while on vacation. Ordered this one when we returned. Easy to put on. Fit perfectly and looks and works better than the old one.
