Out with the old and in with the new. That’s what you should be thinking when it comes to your RV’s water source. Whether you’ve just purchased your RV brand-new or you are looking to make upgrades, a new Alpha tank from RecPro is the best choice for your recreational vehicle.

The tanks from Alpha have a lot to offer for a low price point! For starters they have a low-adhesion property with their tank walls. This means whether you are using this 21-gallon tank for fresh or gray water, bacteria and particulates will have a hard time finding a home on the walls. Low porosity and high-density plastic help to keep these walls virtually detritus free during the life of your tank.

Alpha tanks are solid. This 21-gallon performer is built to last. The tank walls are a 1/4” of an inch thick. Many competitors’ tanks only get to 1/8” If you’ve been on the road for any length of time you know that RVs of all kinds take a ton of abuse. Questionable infrastructure, navigating old campgrounds, boondocking all take their toll on everything inside of your RV. Don’t you think a stronger tank with great structural integrity is a better way to go for your primary water source? At RecPro, we do. That’s why we work with manufacturers like Alpha who offer top-tier items for the savvy RV buyer.
