Hello, I received my order in a timely manner, I installed the parts, the ball, the machine worked very well with very good pressure, but after a few days the price dropped again. Do you have a way to advise me so I can repair my machine?

I restore, buy/sell the older Wagner Diaphragm pumps. Gleem is my go to company for parts. The service is excellent and the prices are very good. What more can you ask for. And now free shipping if you spend $100 or more. Whats not to like.
