  • Get a hose and a funnel
  • Open the lid to the pump
  • Connect the hose to the pipe leading into the pump
  • Pour the antifreeze into the funnel

Your other option is just to pour the antifreeze into the pool skimmer. Avoid pouring any antifreeze into the pool.

Once the winter has passed, and you are ready to use your pool, thoroughly drain the pool antifreeze from the pool’s plumbing system.

Caution: Never use automtove antifreeze in your pool or RV pipes. It is made from toxic ethylene glycol. It should never mix with chlorine. Even a small amount of each will result in a chemical reaction of very dangerous and toxic hydrogen carbon.

What is RV Antifreeze?

RV antifreeze uses the same propylene glycol solution as swimming pool antifreeze. It is used similarly to prevent your RV pipes from freezing in the winter. You use the RV antifreeze to fill the lines in your RV.

This is a good brand of RV antifreeze that is highly rated on Amazon:

Pool Antifreeze vs. RV Antifreeze Differences

Color:Usually blueUsually pink

There is no difference between swimming pool antifreeze and RV antifreeze other than the color. Some brands market their product to be used for both pools and RVs.

Tip: When de-winterizing your RV lines, use a water system cleaner and deodorizers like this one from Camco. It will stop any foul odors and bad taste in your water lines.

Can You Use RV Antifreeze in Pool Lines?

Yes, you can use RV antifreeze in pool lines as they are both made from propylene glycol, which is considered non-toxic by the FDA.

Pool Antifreeze Vs RV Antifreeze Conclusion

We conclude that you can use RV antifreeze and swimming pool antifreeze interchangeably. Your decision on which one to use will depend on the price you’ll have to pay and availability in your area. You might be closer to a pool supply store than an RV store if neither is available to purchase online.

If at all possible, use the product made for your intended use. Instructions for use and how it is supposed to be diluted can differ from one to the other.
