ARO P39344 600 VS Air Filter Regulator Piggyback - The Ultimate Solution for Efficient Air Filtration and Regulation Review

About 6 months ago I cleaned out my garage and added this regulator. It is used very rarely. I only turn on the compressor when using air tools.

It worked fine for a while (about a year) and then started leaking every time the pressure in the tank dropped below the set value. Rare use. Sometimes it can be stopped by increasing/decreasing the pressure.

I have 10 feet of copper pipe and a water drain between the compressor and this unit so not a lot of water gets into the trap but picks up a lot of rust and other crap. When filling this block BE SURE there is some clearance between…
