Antifreeze hose?

[bingraham66]

Is there a hose to the pump to winterize the trailer with antifreeze? I didn't see anything around the pump so thought id ask.

I unhook the inlet from the pump and attach a hose that I made to go in the jug of antifreeze. It's like a 3/4" compression fitting and clear poly tube. Got the fittings and hose from the hardware store.

Some trailers are plumbed with a dedicated antifreeze inlet port, some aren't. For those that aren't people often modify their plumbing to add one. I have one, port is on the side of my trailer near the city water port.
If you specify what model trailer you have, others may chime in with a model specific answer.

It's a rockwood A122.. I'll add a inlet tee like I had on my previous B van

I just blow all mine out with an air compressor to winterize if I’m not using it, quicker now and later and its protected that way down to even arctic temperatures, well below what any antifreeze is rated down to. I do however dump RV antifreeze into my toilet tank with my toilet chemicals during use. Maybe I’m just weird, but I’m terrified of the thought of my black tank freezing and turning into a poopcicle. I have temperature monitors (Samsung SmartThings) on the outside of my black tank as well to warn me if my tank is getting down close to 32 deg F so I have warning to take immediate action. I’ve never seen that tank get below 45 deg F even when outside temps here get below zero, but I do worry about it all winter long.
