I believe it is an older Reinco, I have to see if I can read the tag on it. Yes I was only running clean water through it when I noticed the leaks. The owner wants to use it primarily to water nursery stock and may use the gun. This unit has been stored in a barn, unused for many years and they asked me to get it running for them again. I have no idea how many hours are on it. It seems to run pretty good, had a few other leaks that I think I have taken care of. I'll try and get back to before the weekend and try to get them apart.
