After a lot of lies it was finally MAILED A WEEK LATER, would not do business with this guy. He got real ugly with me and had a bad attitude. I installed it and it did work however next time I will buy a factory part at more money however I know it is new and I Get a warranty. I don't know what kind of quality the diaphragm is, or how long it will last. He said he changes his every 2 years,why if it is as good as a new one? A new factory diaphragm should last at least 10 years, mine was 12 years old and I damaged it while working on the motor, other wise it would still be working. I should have bought a factory part. I may be in the same situation in just a few years, (don't know how long this cheap one will last that he makes himself or so he says) The guy may do quality work, but at this point I just don't know. I tried not to hammer this guy to much, but the facts are the facts. Did he build a new diaphragm? YES
Did he mail it when he said he did? NO
Did it work? YES
Will It last? DO NOT KNOW
Would I buy from him again? NO
Was it a good experience? NO
You will have to make your own decision and of course his side of the story will be different, there are always two sides to every story.
