Frozen RV Sewer Hose Problem

When your sewer hose freezes up, you can try to pour anti freeze down into your holding tank and see if that helps thaw it. This may not always work, so you can put a space heater nearby the hose and let the heat take care of the unfreezing process.

Freeze Proof RV Sewer Hose

Freeze Proof RV Sewer Hose

One of the problems that come with RVs is that they are designed to meet warm weather conditions. This includes the sewer hoses. These hoses for the most part do not handle cold weather very well.

There is a freeze proof hose available and it may not be that expensive to purchase. It is claimed to handle extreme low temperatures down to 44 below zero F. The key to keep it from freezing is to make sure that no water remains in the 15 foot hose after you have finished dumping.

Plus, this hose is made from tough TPE which means that you can drive over it and it will not crack but bounce back and be ready for the next dump time.

Tip #4: Heat tape is a good alternative to space heaters and foam tubing. This tape will help keep your sewer hose from freezing over when it is to in use. Preventive medicine is worth a pound of thawing cures.

RV Sewer Valve Frozen

If a space heater and an RV skirt did not prevent your sewer valve from freezing over, then you may need to use more direct heat measures to get it working again. Two home accessories can really help you out in this situation.

First, your wife’s or daughter’s hair dryer will bring the direct heat you need to thaw out your valve. Just make sure you have their permission before using it. The hair dryer will produce very high temperatures and shouldn’t take too long to thaw out the valve.

Second, the home tool you can use is a heat gun. Like a hair dryer, this accessory delivers the high temperatures you want and need. To thaw out the valve correctly, start at the top and work your way down.

Just do not go to slowly or stay in one spot for too long. If you do, you run the risk of melting any plastic that is on the valve. You may also damage the holding tank region next to the valve.

You may also want to run these accessories over your holding tank to make sure there is no ice inside of it. Just keep the tools moving as ABS plastic is easy to melt.

Tip #5: After thawing your valve and holding tank, make sure to add 1 or 2 gallons of anti-freeze or windshield washer fluid to the tank. Or just add insulation to the valve to protect it from the cold weather
