antifreeze is probably the most misunderstood commodity in our industry
today. There are currently three different varieties on the market
at three very different prices.
Ethanol (alcohol) based:
This type of antifreeze is most readily available in hardware stores and
most RV shops it sells for approximately $3.00 Canadian a jug.
However, this product is also extremely flammable and not to used around
any sort of pilot flames or cigarettes. As well, this product has
been known to taint certain RV plumbing systems and is only to be used
with Quest or Pex plumbing lines. Furthermore, because this product
is made from alcohol it works to dry out all the rubber seals readily
found in your faucets and toilet. As a result we do not recommend or
sell this product.
Propylene Glycol based:
This product is only available at your local RV shop (and not every RV
shop for that matter). It sells for approximately $6.00 Canadian a
jug. Like the ethanol antifreeze, this product is non-toxic and safe
for all RV plumbing. However, propylene glycol does not have the
same fire safety warnings, nor the risk of tainting your RV plumbing
system. Furthermore, propylene glycol is a lubricant and will
actually work to extend the life of the seals in your faucets and toilets,
unlike the ethanol based products. This is the only product we use
on our own RVs and the only product we sell in our parts
Again this product is non-toxic and completely safe for RV plumbing
systems. It will cost more than $3.00 and less than $6.00 Canadian a
jug. This may seem like a good idea, however, it is unknown how much
ethanol is required to taint RV plumbing lines and dry out plumbing
seals. For that reason we do not recommend this product.
