The kit PWI was supplied a good five years ago to a previous owner as an experiment for DI application, I believe we did not charge him. He did purchase the DDS3v10.

I don't understand the reason for the system not to work after a period of no usage. It happened before and I will supplied you with an replacement at pump at cost price. Unfortunately, that was the last one. It worked for over a year.

I think you should consider investing on one of the current system.
