No hot water

[i'm in the R V now]

No hot water or water pressure have been told maybe it's the bypass for hot water heater , I've found bypass behind sink now what?

Have you ever had hot water in this coach? If so, what has changed since it was working.
The water heater bypass is usually close to the water heater and may be in the Winterizing (bypass) position - take a look at this -

just a bit more info will help us help you. what kind of RV. are you hooked up to CG water or using your tank?

If on tank, is the pump running?
If on CG water, are you tied into correct fitting and is the spigot valve fully open.

fix no water issue first, once you have restored water flow to RV you can verify flow path for the water heater.

is this a new rv? has it worked before?
