You’ve looked on Supply House I assume? Call them as they are very helpful on the phone.If we didn’t have 7 people in the house (and before long 5 of them will be teenagers), I wouldn’t be so concerned about tankless. But as is we easily exhaust our 80gal tank (at 130 degrees) and inevitably end up with a cold shower. Never mind trying to balance that with the dishwasher and laundry washing machine.
I have all the info I need for best fit, but I still lack a link to where I can buy a lead free flow switch for <= 0.5GPM (ideally 1” fittings, but can add adapters for anything over 3/4”).
I can find a couple online, but none are verified lead free and I question their quality. Any help here would be greatly appreciated. I’m likely just not googling the right way. All I can find are paddle switches for >4 GPM (too high flow) and reed switches for 0.25-0.5GPM but <= 1/2” fittings (too small fittings).
