"What does shut off at 18' mean?"
It means that the pump cannot pump higher (measured vertically) than 17' 11" (with no friction loss taken into account).

"Can I mount the check valve horizontally?"
It is recommended that the check valve (or check/ball valve combination) is mounted vertically, however each can be mounted horizontally. The installation for each unit is similar; the check valve hinge must be at the top.

"I want to add a toilet in my basement. I want to pump it up (my sewage). However all my drain lines are above. What can I do?"
You can install a sewage ejector pump and basin. There are two ways to do this depending on what you want the finished product to look like and how much work you want to do. The Zoeller "Qwik Jon" can be installed with no digging at all. However, your toilet will sit up on the unit (about 5 1/2" above the floor). If you want to drain any other fixtures into it (lavs, laundry sinks, etc.) you will need to run a drain line from the fixture along the baseboard to the Zoeller basin. We have sold many "Qwik Jon" systems.

"Your price for the Zoeller Qwik Jons seems so low compared to others. Are these complete units? I mean, does it includes the pump and the basin, etc."
Qwik Jon models 100 and 102 are complete. We do not "bait and switch." We have sold many of them, and the volume of our purchasing, and the fact that our overhead is very low allows us to sell the complete package at the low price listed above.

"Can I safely use an air admittance valve (or "auto vent") on any of the above systems?"
Although some people have installed an air admittance valve on the above systems, we will never suggest or recommend that you do so. We always recommend installing a vent all the way through the roof (and as per your local codes). We have had people write us stating that when they installed an air admittance valve the flapper in the valve can chatter and create vibration. The right way to go is to install a non-mechanical vent, all the way to the roof, and as per your local codes.

"How is the toilet mounted to the tank on the Qwik Jon?"
Basically it's as easy as mounting a toilet to standard toilet flanges (99% of toilets today mount this way) in that you simply attach your toilet with standard toilet bolts (identically to standard toilet mounting) to the provided toilet flange.

"What is a vortex impeller and what does it do?"
A vortex impeller handles debris better than other impellers. It's used to help prevent clogging in your pump. Below is an example of a vortex impeller.

"What does the automatic reset thermal overload protection do?"
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.

"Do I need to install a vent pipe to the tank?"
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.
