Talk to a Human
We’re a small business, so your phone call won’t be met with an annoying long phone menu. And your email won’t end up out somewhere on the web, never to be answered.
So give us a call, send us an email, or join us on social media. We love tweets, likes, pins, and follows!
We look forward to helping you upgrade your RV’s waste system, so dumping your tanks is as clean and simple as putting gas in your car.

Shipping to a Different Address
We know that most of our customers are travelling in their RV’s and may not be at their home address so our website makes it easy to ship to a different address.
If shipping to an RV park, do include the name of the park and your site number. Inform the person in the RV park’s office that you are expecting a package and to hold it for you. In some parks the delivery driver will deliver the package to your campsite, and often in this case you will need to be there to receive it.
Another option is shipping your order to a UPS store or depot. Please contact us to make those arrangements.
