Abstract
A reservoir for leak detecting fluid for a tank is disclosed. A reservoir is used with a double wall glass fiber reinforced plastic tank where the tank has an inner wall, an outer wall, and annular space between the inner and outer walls for receiving a leak detecting fluid and an enclosed space within the inner wall for the storage of a liquid. An opening is provided in the outer wall of the tank and the opening is in communication with the annular space between the inner and outer walls. A one-piece reinforced plastic reservoir for leak detecting fluid is positioned on the tank. The reservoir has a sidewall and an end wall extending across one end of the sidewall. The sidewall is secured to the outer wall of the tank with the interior of the reservoir being in alignment with the opening in the outer wall of the tank. The sidewall is secured to the outer wall of the tank by a bead of glass fiber reinforced plastic that is positioned around the outer periphery of the sidewall and extends onto the outer wall of the tank to integrally bond the reservoir to the outer wall of the tank. The reservoir is positioned underground when the tank is installed underground. At least one fitting …
