FREQUENTLY ASKED QUESTIONS

Everything you need to know about the RV Blowout Plug Adapter.

What air pressure (PSI) should I use with this adapter?
We recommend setting your air compressor regulator to 20–30 PSI maximum. Do not exceed 30 PSI to avoid damaging delicate PEX lines, fixtures, or water heaters inside your RV.
Is this compatible with standard garden hose fittings?
Yes! The adapter features standard Garden Hose Threading (GHT) that attaches directly to RV city water inlets, garden hoses, boat fresh water systems, and outdoor faucets.
Do I still need to use antifreeze liquid?
Blowing out water lines with compressed air purges almost all water from fresh lines, eliminating the need to pump chemical antifreeze through your freshwater drinking pipes. (You may still pour a small amount of antifreeze into P-traps and waste tanks).
What material is this adapter made of?
It is constructed from 100% solid brass with a high-grade rubber valve stem and rubber seal washer, ensuring rust-proof, heavy-duty durability for years of seasonal use.
