I live in an area where it rarely gets below freezing for more than a day or two. I am wondering about anti-freeze. I have three drains...the kitchen sink, the bathroom sink, the shower, and then i have the toilet. What would be the danger with he following : Drain all tanks (grey and black and water heater). Open the valves to drain the pipes. Keep them open and pour anti-freeze into each sink and shower until you see anti-freeze coming out through the open valves underneath the RV. Once you know the antifreeze has gone thru each sink and shower, then close up the drain valves. Por some antifreeze into the toilet and black tank.
What is missed vs, using the pump and sucking the antifreeze into the piping ? Thanks
