Complete Gas Vac Mains System
Part# 71-076028
The Gas-Vac Water Remover Gun, is supplied with an in-line one way valve and a vent stack (which vents to the atmosphere via a flame trap) It is connected to the outlet of the 10 gallon water collection container. The inlet of the water container is connected to the main or drip pot to be dewatered using a clear flexible hose which terminates in an adapter.
When the trigger on the Gas-Vac gun is activated, a vacuum is created within the plastic container, and the water from the main, or drip pot, is drawn into the container. The container, which is negative pressure resistant, is constructed from opaque white plastic, which enables the operator to see the amount of water extracted.
For direct connection to a drip pot, the Gas-Vac attaches to an in-line ball valve, which ensures the flow of gas can be controlled after the drip pot is emptied. In the case of drip pots with corroded dip-pipes, a length of nylon tube is supplied with fittings that enable a no-blow insertion into the existing dip pipe. This nylon tube enables the operator to reach water at the bottom of corroded dip pipes, which would otherwise remain in place.
