Q. "What's the difference between an automatic and non-automatic pump?"
A. An automatic pump has a built in float switch that will turn on the pump automatically at a fixed water level. After the water is pumped out to certain water level (also a preset level), the pump will turn itself off. A non-automatic pump has to be manually turned on and off, or with a separate control like a piggyback float switch.
Q. "What does the automatic reset thermal overload protection do?"
A. If the pump gets too hot the thermal overload protection will turn it off until the pump cools down (to prevent damage to the motor). The pump turns back on after it has cooled down enough. This backup protection feature is useful if some debris causes the pump to overheat.
Q. "What does progressive cavity mean?"
A. This type of pump transfers fluid by means of the progress, through the pump, of a sequence of small, fixed shape, discrete cavities as its rotor is turned.
Q. "Why is it called a submersible pump?"
A. These pumps are designed to be placed directly in the water. They draw the water up from the bottom of the pump.
Q. "Do I need to install a vent pipe to the tank?"
A. It really depends on how you plumb the piping to the tank and each situation is different. In many cases with any brand of sealed tank the simple answer is yes as you need air to displace the volume of discharge. An AAV may be used in many areas of the country but local codes always prevail and so best to check with your local code authorities before purchasing the enclosed tank system/s such as these shown on this page.
Q. "What does it mean when it says the basin comes with a 10' stack test steel cover?"
A. It means the basin and lid have been tested to withstand water pressure from a 10 ft. vertical pipe (stack) without leaking.
Q. "Can we order the 915 grinder system without the basin for a retrofit application?"
A.The 915 grinder systems are always shipped with the basin. The basin is also the shipping container to protect the entire internal system from damage. For retrofit applications, just remove and discard the basin.
