Custom made WI with a fail save system (see drawing inside)

I don't have any problem with the rest of the system, well thought out. Just curious how the failsafe works. Now I know that you did not include the clog-jet switch, that is fine. Something you will include soon.

If you are using the float switch, ensure the float will float with methanol. SG=0.79 approximately.

How much are you planning to spend on your system? It appeared you have already invested a great deal of components. They are all good stuff.

I have no objection where you get your part from - I help you to see this through to the end.

I do have one more useful suggestion. Does you pump have a demand switch?
