Maintenance (Continued)
10. Pull lip ring of bladder through tank
opening and seat it against tank
head.
11. Clean sealing surface and groove of
cover flange; place on tank (See
Figure 20).
NOTE:
Be sure elbow lines up with hole
in base.
12. Tighten nuts as follows:
a. Hand tighten all nuts.
b. Tighten one nut snug.
c. Tighten opposite nut snug.
d. Proceed, tightening opposite pairs
of nuts to a snug fit.
e. Recheck all nuts, using same
pattern. Be sure all nuts are tight
and that you have a good seal.
IMPORTANT:
Do not overtighten; you
may twist studs off of tank. If you have
a torque wrench, tighten to 85 inch-
pounds of torque.
13. Stand tank on feet and reconnect
piping.
14. Recharge tank to proper air
pressure.
15. Prime pump (See Page 9).
TO CHECK TANK AIR CHARGE
If drawdown (amount of water that
comes out of tank per pump cycle)
decreases significantly, check as follows:
1. To check air charge in tank, shut OFF
electric power to pump, open faucet
near tank, and drain completely.
2. At the air valve in top of tank, check
air pressure with a standard tire
gauge. Air pressure should be 2 psi
below pump pressure switch cut-in
setting.
3. If the air pressure is more than 2 psi
below the cut-in setting, add air to
the tank. Use an air compressor or a
portable air storage tank.
4. Use soap or liquid detergent to check
for air leaks around air valve.
Continuous bubbling indicates a leak.
If necessary, install new core in air
valve. This is the same as those used
for automobile tubeless tires.
HOW TO HANDLE A GASEOUS WELL
If well water contains gases, suspend a
pipe, closed at the bottom and open at
the top, so that it surrounds the suction
pipe inlet (See Figure 28). Since the
gases rise in the well casing, the water
sucked down through the pipe and into
pump suction is gas-free. This type of
well must be vented to the outside of
any enclosure.
