No matter the home, Grundfos makes installation easy.

Newer homes may already have a dedicated return line installed. Older homes may not. Grundfos offers the right pumps for all types of plumbing to deliver immediate hot water.

Homes without a dedicated return line

Most older homes in the US were built without a dedicated return line. For these, a retrofit solution uses the cold water line to give you the convenience you want without having to change your plumbing. The Grundfos Comfort System includes all the components needed — the pump, hose kit, bypass valve and digital timer. Installation can be completed in less than two hours.
