Update to previous review. I want to give a shout out to the manufacturer Cartlee. Let it be noted I never contacted the company about my issue. They contacted ME!. During the HOLIDAY'S!. Taking the time from their family to rectify the issue I was having and went out of their way to promptly get me up and going. This is truly a quality product that I was very happy with until failure. It does what it's supposed to do and the fluid filled pressure gauge is a bonus. In a perfect world everything you purchase would last forever but I know even quality products can have problems at times. What makes the difference between the have and the have not's is the customer service that follows your purchase. This product and the company is top shelf in my book and deserves the updated rating.
Previous review: Purchased from Amazon in May and based upon reviews and description of product this seemed like the one to get for my needs. First time I used it worked as advertised. Bumped it up to 50 psi and worked like a charm on the RV. This week, second time out, noticed leak at fitting behind commode third day into trip and had to turn water off to troubleshoot. YIKES! Thank goodness I bought one with a gauge. This thing was pegged at 90 psi. No wonder I had a leak and lucky didn't pop a line. Backed off regulator screw all the way and the lowest pressure I could get was 68 psi. Had high hopes but it's a shame it didn't last long.
