Pipe for the Drain Flood Protector (Standpipe Model)

Standpipe Model

The Drain Flood Protector standpipe version without a float is available for 3" and 4" drains. The standpipe models are recommended for more extreme or extended pressure situations. In the event of a backup, water rises up the inside of the pipe. The length of the standpipe can be made the length you determine you will need it to be to offer the best possible protection for your situation. Your standpipe height should be higher than the highest point of flooding elevation you have experienced.

However, in some geological locations and severe flood conditions, your basement may need to flood to equalize the pressure inside your basement walls to that of the pressure against the outside walls caused by excessive groundwater. Standpipes that are too long run the risk of preventing the basement from flooding when it’s absolutely needed to prevent walls or floors from cracking or the possible collapse of the basement walls. We strongly suggest you consult local codes or an expert to determine the ideal height for your standpipe in your area.

How the Standpipe Model Works

To install the 3" standpipe version, the Drain Flood Protector has a rubber gasket the standpipe is inserted into and both are then lowered into the drain pipe. The screws are fully tightened once it has been lowered inside the drain pipe to ensure a tight seal. The rubber gasket will receive 1-½" PVC, ABS, galvanized or other iron pipe sized piping like stainless steel or brass. The standpipe must not have an outside diameter greater than 2".

The 4" standpipe model is threaded, and takes 1-½" IPS pipe, galvanized, stainless steel, brass and ABS or PVC male adapters. The standpipe can be connected before or after the Drain Flood Protector's screws are tightened into the drain.
Be sure to highlight the location of each standpipe with bright tape, ribbon or something else - they can be difficult to see, and far too easy to walk into or trip over.

Optional:   Add a Threaded Pipe for the Drain Flood Protector (4" Standpipe Model).  This 12" long, PVC 1-½" IPS pipe is already threaded on one end.  It is needed for the Drain Flood Protector (4" Standpipe Model FG-S-4F).  Save time and hassel on going to the store and buying pipe and cutting down to size. 

*If you can't get a tight tight fit, try wrapping it with this special rubber tape we offer here.
