A compact continuous flow energy efficient gas fired water heater/boiler for use in residential, commercial and industrial buildings wherein cold water enters the heater and flows downward through an outer annulus and then rises up through an inner annulus around a central gas flue, and wherein ...
A transfer conduit accommodates the flow of hot water from the upper chamber to the lower chamber when water is discharged from the lower chamber through an outlet pipe. When the water in the lower chamber cools, a pump returns it to the upper chamber for reheating. The pump and magnetron...

in FIG. 1) wherein both flow paths 60 and 62 are open. This intermediate position prevents an abrupt change in water flow direction to avoid any hammer effect or "dead head" during switching of valve 10. The curved shape of sealing rims 80, 82 further allows a gradual changeover in ...
that fits easily into the conduit onto the end of your snake and use it like a slap hammer to break through the blockage. If it is a lot of dirt then you can use water to flush the dirt out and then remove the water, but I would not want to do that with cables in the conduit...
