Water pump won't pull Antifreeze from the jug.

Stupid question...do you have the valves lined up correctly (line from fw tank closed, line from jug open), and are the low point drains closed?

When you turned the pump on did you have a faucet open? You have to have a faucet open in order for it to work.

You installed it as shown here? youtube

..

you did put it on the input side of the pump? do to design/construction I had to mount mine on the output side and then used a boat bilge pump to force AF in. and of course you had the valve turned the correct way?

Since we don't use the water pump a lot, we always have to prime it when we winterize. Get a small funnel and pour antifreeze into the intake tube while running the pump. After you have antifreeze going through the pump, put the intake tube into the jug. It takes a bit, but has always worked for us.

this is what I have to do to one of our TT's

I had the same issue. Replaced the pump. No joy. Works fine for water use. I ended up first draining the system by use of the low point drain (in my case the shower head on the ground), and then using a jump starter with an air pump to blow out all the lines. I give it 10 seconds to come up to pressure, then I open it quickly. I do it 3-5 times per line. Ended up being cheaper than pink pop. Still have to do the drains though.

Yes to all the above, except for the compressor idea. I used the funnel, pump was trying to compress the air in the system. Had to run inside and then open a faucet.

The only time I have ever had a problem drawing water from the water tank below the floor or from the jug of antifreeze when winterizing was due to a joint upstream of the pump leaking and drawing air not allowing the pump to pull the liquid.

Once I tightened the hose clamps or retaped the joints the pump pulled the liquid fine.

Don't forget to retighten the strainer bowel too.
