Does this work with the watt premier ro system?

Yep, more specifically for an watts RO pure plus system. Just installed one of these and it worked without any issues

How do i connect it to watts premier wp-5? The system gas it's own aso inside, air-gap faucet and tank line is 3/8, not 1/4?

If your supply/ return lines are 3/8ths od and the valve is 1/4 od this is probably not the valve you need, suggest you contact the manufacturer of your filter for a suitable replacement

Is there any warranty on this?

This has worked very well for me since purchase some years ago. It replaced a defective unit on my RO system. At the price point - if it died now at 4 years - I'd have no complaints. But it marches on. So just drop the hammer on it, and move on.

Have 5 stage ro, upgraded tank to 80 gallon. works fine. now added 2nd membrane and 2nd 120 gallon tank. reject water never stops. how to fix ?

It needs to be able to build pressure for it to shut off. Your tank may not be building any pressure check to make sure you don't have any leaks in the tank
