Have the Seaward 20 gallon hot water heater. Are there any tricks to drain hot water tank for winter? Last year it seemed we only had 3 or 4 gallons to drain. This year, more like 18 after running the pump to the point of sputtering faucets. Even with the drain valve open all the way, it seemed like it trickles out very slowly. VERY SLOWLY! I put a shop vac next to it, leaving a tiny gap for air, and it really speeded it up, but it's only a 3 gallon one, so would close the valve after the 3 gallons, empty the vac and repeat until done. and that meant considerable time wedged in the cramped space. I hooked a short bit of hose to see if it would drain out (didn't) but didn't try it with the vacuum. Any short cuts or tricks to make it easier next year?
