Don’t Bypass Important RV Water Heater Steps

Birds chirping in the trees, the gentle rustle of the breeze rippling through the leaves…the sounds of an angry RV’er in the next campsite shouting that the water heater must be broken because there is no hot water…

Ahh, the sounds of the start of another camping season!

But just because your water is not hot does not mean your water heater is broken and you are facing a hefty bill– in 8 out of 10 times, it means that you forgot to reset the Water Heater Bypass Valves!

Those valves, usually in sets of three, are there to protect your water heater from winter’s freezing, while still allowing you to winterize the rest of your RV’s plumbing. Without them, you would need to fill the entire water heater (5 -10 gallons!) with antifreeze in order to properly winterize…. The bypass prevents that, by…well, by BYPASSING the water heater with a few shutoff valves. It prevents water (or antifreeze) from flowing into the water heater.

Now, this is a typical set up. Some RVs which were built without bypass valves will instead have a short piece of tubing that has to be uninstalled. And of course, in the minority of cases there may be another issue, such as the propane shut off, or in the case of those without automatic ignition, the pilot might be off.
