Troubleshooting
1. The red band is showing in the leak detector.
a. Remove the leak detector from the tank by pulling up out of the sealing
rubber bushing and observe the amount of fluid (oil or water) visible on the
end of the detector tube.
b.
If the amount of fluid on the tube is less than a few inches it is nearly always
an indication that fluid has seeped into the interstitial from the top of the
tank from overfilling the tank.
c.
If the amount of fluid on the tube is close to or equal to the amount of oil
in the inner tank then it is an indication of a possible leak in the inner tank
and the installation needs a closer inspection. Call Roth Industries Inc. to
arrange such an inspection.
d. Fluid can removed from the interstitial (space between the two tanks) with a
hand pump or with a long rod that has an absorbent material attached to it
if the amount is small. The cleanup can be finished by using oil absorbent
powder, which will also remove most of the oil smell.
2. Oil smell near the tank
a. If there is the presence of oil of the top of the tank it is an indication of:
1. Leaky pipe joints. Contact an oil service technician or plumber.
2. Plastic cap nuts are loose. Hand tighten or mechanically tighten
to 18 ft-lb of torque.
3.
Overfill during filling. The oil company should be notified about
this leakage and to verify that the Vent Alarm is working correctly.
b. If no oil is visible on the top of the tank then the following must be checked:
1. Plastic cap nuts nay be loose. Hand tighten or mechanically
tighten to 18ft-lb of torque.
2.
The fill and vent piping is not plumb causing unequal pressure
on the o-ring resulting in an air gap on one side of the o-ring.
Contact your oil service technician or plumber.
3.
Compression fittings on the duplex bushing may be loose.
c. Check the leak detector and following instructions above if red band is
showing.
3. Tank sides are bulging and creases have formed on the sides of the tank
a.
The sides of the tank may expand up to two (2) inches per side when filled.
This is a normal condition.
b. Tank sides bulging more than normal is an indication of one of the following:
