Have been successfully using for 30 consecutive days at a campground with very high water pressure. Despite previous cautionary reviews/warnings, I have not yet experienced any problems or product failures.
After a broken water line, a bill for $300 to Leak Detection and their discovery that we had just shy of 100 pounds of water pressure coming in from the street, it was easy to see that our ongoing problems with bursting garden hoses could easily be eliminated by installing pressure regulators on the hose bibs around the house. So far, so good... just screwed these little guys on, attached the hose and the pressure on the garden hose is now manageable... this little device reduces the pressure to 40-50 pounds (plenty for any hose) and should pay for itself by not having to replace burst hoses every six months. Made from brass in the USA, this seems to be the answer to our problem.
I have blown out two XPro hoses, the ones that stretch when you tur. On water. Pressure too high or hoses poor. Bought this to reduce the pressure and so far the hose is working. Not quite as much pressure as I'd like bur enough to water plants etc. definitely a solution for my problem.
We bought this last year for our travel trailer and have only used it a few times. Sometimes we do not need it depending where we stay. We have no complaints on the quality of it when we do use it. It seems to get the job done. The great prices at Walmart make it even better.
For the money this is excellent. I have this one but I am going to purchase a regulator that can be adjusted and where I can see the water pressure. Different camp grounds have different water pressure and it would be nice to see and adjust it.
Bought this at my local Walmart today and installed today. Worked Ok for a couple of hours. My wife took a shower with no problem. I let the RV water heat back up then took my shower, or at least tried to. After about 30 seconds the water just shut off. I turned the faucet off and waited a few seconds. I turned the faucet back on and had water flow for about 3 seconds then it quit again. My wife tried a sink faucet and after a few seconds it quit. Finished my shower using the fresh water tank and the water pump with no problem. After, I went outside, disconnected the hose from the RV, turned the water on, heard lloud hammering and felt pulsing at the hose end, then the water quit. Removed the regulator and put the old regulator back on. Everything now works fine. I have never had a regulator problem before but do change the regulator every couple of years just to play it safe. I looked at the reviews for the same regulator on Amazon after this fiasco and guess what; several people had the same or similar problem. Will return it to Walmart tomorrow and replace with a non Camco regulator.
I had purchased two. First one failed while in the shower soaped up. Second does not deliver very much pressure. Purchase a Valtera adjustable with a gauge, set to 45 psi and worked fine. The second Camco could not have delivered more than 20 psi.
I have owned 2 of these regulators and they both failed after about 2 camping trips. I would not recommend it.
Honestly? A water regulator intended for potable use in an RV, and it contains lead?!? Returned it...
