Hi Guys,

My 28 Riv has a hot water tank that can be heated with shore power or by one of the water cooled engines - through the heat exchanger. We think there is a break in the heat exchanger and that water is escaping.

Here is our plan, but I need some help.

1. We plan on disconnecting the hoses from the engine at the hot water tank heat exchanger connections.
2. We will install 2 valves on the connections on the hot water tank for the heat exchanger (this will close things off).

Question. Can I cap off the two hoses to/from the engine or do they need to be in a loop? The problem is it is pretty tight in there and connecting the two hoses in a loop is pretty challenging.

Really appreciate the help

thank you
