CHECK VALVE

[ljensen]

I want to buy a spare one on line can some one give me a model , part number and where to buy it on line. I have a 07-3400 mine is ok but it sounds like I should get one. What does this thing do that is behind the pantry? Is it a back flo valve or diverter or check valve I am confused Again! Thanks

Go to PPL Parts, they are generic, so the check-valves they have are OK, The pantry location is for the Back tank sprayer, it is a back-flow preventer.
This may help:

I would get the part number for a good brass unit (about $25 cost) and not the plastic one that comes from the factory. We got our 3455 in Feb 2011 and the plastic one that came from the factory was delivered defective on my unit. The repair guys at Mike Thompson's recommended changing it out for a brass one which I did under warrentee for labor (happy to pay the $25 for the non wareentee replacement). Hopefully, no more problem.
