Super Tech RV & Marine Antifreeze Easy Installation, Corrosion Protection Antifreeze & Coolant Gallon Bottle (1 Pack)

This works well for homes also. I leave for extended periods of time, and it's not the cold I worry about, but the heat - during the summer, the water in my p-traps for the sinks, tubs, toilets, and washing machine will dry out. This allows sewer gas to back up in my house unless someone is flushing the lines with water to replace that that dries out. Using this product prevents evaporation, and as such, I now no longer come home to my home smelling like sewer gas. Simply pouring it down the drains/in the toilets prevents the issue. The cost, and ability to simply flush the product out of my drains when I start using the plumbing makes it a no-brainer for me.

This antifreeze works exactly as expected and is easy to use. The odorless formula is a big plus, and it provides peace of mind when winterizing RV or marine water systems. The container pours well with no mess, and the price is very reasonable for the quality. It's a dependable product that I trust and would definitely purchase again.

I was not able to pickup. My husband picked up. He had to call me with the pickup space number then I went on the app to send info to Walmart. Maybe there's an easier way to allow the person picking up order to directly communicate with the store's team

Living in a RV during winter and using 2 gallons per tank and only flushing about 1/4 of the tanks..helps the 45 gallons not freeze while running all sinks with a heated water hose allowing it to solid drain 🥳

Tasted pretty good, a little sweeter than I had anticipated but this drink did keep me warm during the winter months. Just bought my second batch for this fall and winter! I didn't give it 5 stars because I did have some indigestion, but it beats freezing to death.

Works well in our RV and our cabin. We have used it for years with no freezing pipes down to -30F. Pour it in the pipes and forget about it until next year. Walmart price is cheaper than other places but it seems to increase every year above the rate of inflation.

It was not that long ago that this RV antifreeze used to be a decent price. It is sad how much is going up overtime and I can't think of a reason why lame excuse excuses lies, and greed. Is sad everyone wants to be rich overnight and never achieve happiness.

The cap is tight and the seal is extremely hard to open, as a result, I spilled some of it on the floor and sofa in my RV when I opened it, which is the last thing I wanted to happen. I really wish these products were designed with ease of use for the consumer in mind.

Went to store website said plenty in stock get there only 2 gallons available. No one of any confidence could help. Went back ordered online same day delivery with delivery charge and driver tip only to be towed not in stock order canceled re-ordered from different store free delivery no driver tip, but had to wait a day for the delivery would be nice if you could update your webpages and have good stock accounting. This is why Walmart is falling behind. Amazon would love again try to patronize in person and while in person purchase other items which I would not have done online in the future I question whether I would go to the store and you would lose the additional purchases.
