where's the water coming from?

[Papa John]

When I open the doors to the van in the morning there is a puddle of water at the base of my 370.
The heat exchanger overflow, bypass and overheating valve all return back to my fresh water tank.

Check your GP pump head fittings

Is your chem mix jug over flowing?

Pin holes in any hose?

Homeless person living back there?

 

[Papa John]

Sometimes the Chem mix jug is the cause.
I think the Chem flow meter drains into vac port and onto floor. I'll have to look for pin holes.
