Depends on the product and the un-loader. There are a few valid reasons for heel, but it should be rare. Most common reason is driver/loader doesn't check for heel. Even experienced drivers can skip this step.

Ya i think my drivers are being lazy and not checking,,, the product is some snotty stuff and was on a rear unload, and aired off making tons of foam. That could be it as well

S.O.P. for a thick product like polymer is to shut off the external valve once the hose jumps but leave the internal open to let the product ooze down the sides and fill up the pipe under the tank. Wait about 30 minutes and crack the valve just a little until it blows dry again. Do that a couple of times and you can get all you can out. A real foamy product might make too big of a mess to allow that.Oaker Thanks this. -
As a non-tanker-yanker, can someone tell me what heel is? I'm curious.

I've had times that I had to drop the trailer with blocks under the trailer dollies. Then when nearly mt, jack up the trailer to get more of an angle to help the product flow. You can also get a setup that with bypass the tractor leveling valve and allow the air bags to inflate until it stops rising at the end of the shock travel. Gives and extra 2 to 3 inches of lift. Can make a big difference. Just make sure to lower it back down before you leave or you'll be hearing some interesting noises. And yes heel can be super expensive. Even on benign products tank washes charge 415 a gallon and up for anything ove 5 gallons.

We were always told to notify dispatch prior to departure if there is a heel. If you left consignee with heel and didn't notify you bought disposal fee and lost all demurrage.

Thick products can be a tough one as we all know. It can be easy to not see heel when it's a rear. Couple that with foam, yeah I'm sure many on here could miss it.

Used to haul whale snot goo called liquid animal feed. Air it off. Once it allegedly went empty, you had to close all valves, drop the hose and drive around the customer parking lot to try to get some the clinging product to drop. Total PITB.
But that was one particular product and customer. Normally, if there is more 5 or 10 gallons, that's on the driver. But again, every situation is different.
