Well I received the item in a timely fashion. Package was nicely wrapped and no damage to the parts inside. However, I did not receive the screws, the o-ring for the mount base, or either of the smaller check valve gaskets. Called to get the correct parts and no one working that day could help. Luckily I was really only after the bigger diaphragm gaskets and was able to make it work. If I would of received all of the parts, and was able to speak with someone who could help. I would of gave a 5 star.
I apologize for this experience. Customer service and tech support are available Monday thru Friday 8-5 and tech is here until noon on Saturdays. I will send a message to customer service for you to have the missing parts sent out.
