ok, that is good confirmation!

So then i will install the two valves i have on each leg and will have the 
option to close the circuit to the water heater. The cooling system will see 
deads ends just like the plugs on the engine.

Thank you all. This list has done it again!

Hi,

I just remove a air heater that was nstalled by premious owner. It was T in the 
coolant hoses going to the water heater but never woeked well. I guess the 
hoses running in the bilges was too much of a heat loss.

So anyways, i'm going back to original and simplicity and i remember somebody 
here said he added valves to have the option to "bypass" the water heater in 
case of a leak. Since i already have the valves and my tank is original it 
seems to be a good idea. My question is: can i just install them in line on 
each hose or do i need to add a loop before the valves with T fittings , engine 
side of the valves, so i still have circulation. I think it does't matter and 
that the engine system does not depend on this but i want to be sure.

Thank you.
