Go ahead and ask us anything.
Hi Seth,
thank you and just following up with you about this message aboved. I'm looking forward to hearing from you thanks Mac
I am not too familiar with this type of scenario, I am going to ask Shaun if he would be willing to answer this question as a public ticket so that we can help others looking for answers in the same type of scenario. Would this be agreeable? This way we can help others as well! Let me know what you think!

Pumps are tough because they do tend to throw magnetic fields. The magnetic field is from the motor - the windings of course - and the electric field is from the AC power. The electric field is between the earth and everything on it (building materials) and the "hot" conductor aka ungrounded conductor. Shielding and grounding really aren't an option inside of a tank like this. So the pump is submersible and actually sits in the drinking water for the cat?
You could reduce the electric field by connecting it to an isolation transformer. You would only need a very small one too, so that is an option. This floats the hot/neutral going to the water tank so they don't have a reference to ground. Would also help protect against electrocution too.
Cats seem to love EMF, but dogs and people don't. As for magnetic field, you would have to build a tank that you could then shield with magnetic field shielding material like mumetal and giron. You can't put those metals inside the tank - they would need to be on the outside of the tank. Another solution would be to install an occupancy sensor and have a contactor that defaults to off. Then you could detect when you or the cat are near and it should turn the pump off. Complicated to setup, but would work. Then when you leave it would resume recirculating water.
