Delta Traditional Wall Mount Pot Filler, Polished Nickel

Love my pot filler 1177LF ! Delta however does not offer replacement o-rings when it started leaking but I found what I needed and repaired it. I disassembled my leaky pot filler and measured the o-rings in the arm joints where it was leaking with a micrometer. There are three o-rings per swivel joint. Based on my measurements I ordered Rubber O-Rings size 20mm OD - 14mm ID and 3mm Width from AMZ. You need six but order extra if you damage one during install. The replacement was easy. Turn off the water at the valve closest to the wall. Open the valve at the end to drain any water. Pop off the decretive caps and using a proper size allen (hex) wrench unscrew the connection at the wall valve first. Remove the pot filler. Unscrew the second joint. Remove the old o-ring that is closest to the threads on the brass insert first. Then remove / unscrew the insert completely. You may need to gently push it out with a wooden dowel and rubber mallet. Remove the last two o-rings from each insert. Clean any mineral buildup from ALL parts. I used white vinegar. Dry then lube ALL parts with a small amount food grade silicone grease before and after installing the o-rings to assist with assembly and o-ring wear. Replace just the first two o-rings farthest away from the threads first. Install the inserts back into the pot filler arms. It will be a tight fit. This is where the silicone lube and rubber mallet if needed come in handy. Use a wooden block or socket so you do not damage the brass threads when pushing the inserts through and out the other side. I also slowly twisted the insert with the hex wrench while pushing back in to prevent o-ring damage. Once they are all the way through add the last o-ring. If you try to put all three o-rings on first you will damage the o-ring closest to the threads while pushing the insert back in. Re attach the filler swivel arms pieces first and then the filler back to the wall valve. Tighten securely but do not over tighten. Check for leaks by shutting off the outer valve and turning on the wall valve. Retighten with hex wrench as needed. No leaks? Replace the beauty caps and run the water in a large pot to flush out any excess grease. After replacing the o-rings my pot filler was a bit stiff to move but no longer leaks! :)
