Pipe Length Affect on Suction
I have just put on an addition on my house. I have an existing electrolux system. It has two inlets. One in the original part of the house and one in the basement. In order for me to add an inlet from the addition I would have to go from the inlet directly up to the attic and then down into the basement. Is this possible or would I lose suction power.

Thank you for the question, Mike. Adding pipe up to the attic and then back down to the basement will not cause any noticeable loss of suction. Use sweep 90s, not tight 90s (except at the inlet), and use 45 turns where you can replace 90 turns. This will keep the suction as pure as possible. When it comes to feeling a loss of suction, that will also be affected by the total length of the pipe run from the main unit to the farthest inlet. For your unit you'd want to keep that run below 125 feet. Each 90 turn adds 5ft of "pipe" or friction loss, so take that into account when adding it up. But it sounds like you will be perfectly fine. Plus, the motor, filter, number of elbows, and diameter of hose all play apart in this so it's a bit of an art.
