Frequently Asked Questions

Q. "What is the QuickTree System?"
A. The QuickTree System includes a stainless steel float tree, pre-mounted pump float and an additional clamp for an alarm float. The tree hangs down from its holder underneath the basin cover, allowing easy access and removal of switches without disturbing the pump or other plumbing.

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.
