Replacing coolant hoses to water heater

[buddybear]

In the process of changing the coolant hoses from the engine to the water heater. On one of the hoses at the water heater there is a plastic inline bleed valve. I have never used this when bleeding the air from the system after changing coolant. It is in a location where it is not easily accessible. All of the bleeding I have done is in the engine compartment. Any reason why I can't just eliminate this valve and plumb the hose directly to the fitting on the water heater. It would make installation easier. as I said earlier I have never even turned this valve.

Thanks,
Mark

No reason at all if you have not been using it.

As long as your procedure has been working, that is one less hidden failure point on the lines.

Bleeding (or as we call it Burping) is required to get air out of the hoses between the heater and the engine because the freshwater coolant pump on the engine cannot pump air, only water; if air is in the line, the engine WILL overheat.

Bleeding can only be done at the high point of any pipe/hose loop.

In some boats the heater is above the engine, so a vent at the heater will work.

In other boats the heater is below the engine, so the vent at the heater is useless. The vent at the engine is usually on top of the thermostat; others, like me, choose to fill the hose to the heater with coolant manually to eliminate the air.

Your boat, your choice.

I fill the hose to the heater manually as you do and it has been working well.
Thanks

Thanks, that is what I thought
