I can't get a pump to prime. It is a 1/2 horsepower (Wayne) Sallow Well
Pump. I hvae it mounted on a small tank that has a bladder inside. There
is water in the well . . . about 5' below surface. The check valve is
ok. I even hooked a garden hose to the spigot to make sure it got enough
water. Still no dice! The tank has about 15 pounds air pressure. What am
I doing wrong.
I await your expert input.
Generally the suction line from the pump to the well has to be full of water
before the pump will draw water. There are some pumps, I guess, which will
eventually clear the air in the line but most will not. If the suction line
is full of water, however, the pump should start to draw. I assume that the
check valve is at the end of the line, down in the well; is it? It may take
some patience to get the line full. Do you have a tee at the pump so you
can pour water into the line? You would pour water into the tee and wait
for it to go down, then pour more etc. The line probably does not have to
be completely full but it has to have enough water so that when you pull it
into the pump the water in the well follows in sufficient quantity to
maintain the suction.
