Re: Manual water pump priming sucks so much ....
Most diaphragm pumps are self priming to about 10'. I've used the Shurflo Washdown pumps for everything on the boat (fresh and salt), industrial equipment, construction equipment, etc and they are bulletproof (and relatively inexpensive). You can rebuild pumps but new and reliable works for me.
Edit: disregard, didn't realize you had a manual pump.
