How can I determine if the tubing quantity in the Manabloc Package is enough for my project?

A. We use 25' as the average fixture run length for the tubing quantities in the Manabloc Packages, then round up to the next hundred (shortest coil available is 100'). 25' average per fixture run is usually enough tubing for most relatively efficient floorplans, but if your home is spread out, has multiple floors or has extra fixtures (dual Lavs in bathrooms, laundry sinks, separate tubs & showers, etc), you will need additional tubing. The simplest way to figure tubing quantity is to scale the horizontal fixture runs from a blueprint (make sure to measure the same path that the tubing will follow), then add the vertical distance from the floor (or ceiling) to the Manabloc and the vertical distance from the floor (or ceiling) to the fixture.  more
