Here’s a question from a reader of RVtravel.com about boondocking. Do you have a question for Bob? Email him at bob.rvtravel (at) gmail.com .
We do a lot of camping at beaches.When the kids take baths, lots of sand gets washed in the shower. Should I be concerned that there will be too much sand in the grey tank that one day it will cause a problem? Thanks. Robert
A problematic buildup of sand in your gray tank is unlikely, though possible. However, the following tips may not only keep the problems at bay but will also give you more peace of mind.
(1) Rinse off the beach sand from your kids (and dog) with your outside shower before they enter the RV shower. If you don’t have an outside shower, a Sun Shower (photo) will work. This will get rid of most of the sand. And don’t worry about the scouring effect of sand — it would need higher pressure than gravity to act like sandpaper.
(2) Only dump your gray tank when nearly full. The pressure of the outflowing water will carry the sand and other debris with it.
(3) Every few months or at the end of beach season dump about two buckets full of water and a bag of ice cubes in the gray tank and let it slosh around in your tank while you drive to the next campground or dump station. The ice cubes will break up the more solid components of your tank and will then melt to be easily dumped at the next dump station. This will also help break up other solids that enter your gray tank from the kitchen sink.
(4) If you still question whether your gray tank is getting a buildup, it may not be the sand but kitchen waste. If so, do number (3) above but also add about a half cup of dishwasher detergent to the tank. This will help to break up those nasty (and smelly) kitchen odors. After you dump this mixture, fill the tank with fresh water and drain again to get rid of the soap and whatever is left.
