❄️ VIAIR 90145 Winterization Kit for RVs Review

Yes, they're expensive, but they seem like a better quality than buying parts at the local hardware store. In combination with a ViAir compressor you have everything you need to blow out your air ducts for the winter.

This kit increases the required size of my Viair compressor which is a must have tool when towing/traveling with my RV. One would think that the price of the compressor would include it.

Hard Freeze here this weekend - Hope it worked - If you're working alone then you need to do something to keep the compressor running while your every faucet etc wasn't tricky but needs to be added to the instructions as the Viair compressor pistol grip does not include this

This kit works great although in my honest opinion it's quite expensive and I think it should be included with the supercharger. However, this winterization kit was easy to assemble and use. I was able to winterize my Class A RV in less than 30 minutes.

I used to use a shop compressor with a built in regulator. I had some concerns about pressure drift during operation. This setup takes care of all uncertainties. I can control the actual pressure at the entrance to the dwelling because the conventional part is light and can therefore be connected directly to the inlet in the RV.

Regulator Does Not Regulate. Whatever air pressure came in, it immediately returned from the other side, no matter how the adjustment knob was set. Possibly poor factory quality control. It's no good trying to winterize your RV. I previously wrote by mistake that the case is plastic, which was wrong. It's a metal body, but that doesn't take away from the fact that it's not adjustable.
