Frequently asked questions
Is a variable speed pump worth it?
Variable speed pumps draw dramatically less power at low speed because energy use falls far faster than flow does. Many jurisdictions now require variable speed for new and replacement residential pool pumps above a certain horsepower, so check local code before buying single-speed.
What is the part number for this pump?
Pentair lists this pump under part number 356879Z. Quote 356879Z when you cross-reference against your equipment manual, an existing part, or a parts diagram, so you are comparing the same revision.
How do I match a pump to my pool?
Work from the plumbing rather than the pool size: line diameter, total dynamic head and the flow your filter and heater can accept all cap the useful pump size. An oversized pump on undersized plumbing wastes power and can exceed the filter's rated flow.
How do I confirm this fits my equipment?
Match the part number stamped on the component you are replacing, or look it up in the parts list for your Pentair equipment. If your model or serial number is not named on this page, send it to us before you order and we will confirm the fit.
What do I need to check before installing this pump?
Confirm the voltage, the union or port sizes and the mounting footprint against your existing installation. Pump replacement usually involves electrical connections and may require a licensed electrician depending on local requirements.
Is there a warranty on this pump?
It carries the standard Pentair manufacturer warranty. The terms are set by Pentair, and on some equipment the coverage only applies when a licensed professional performs the installation. Keep the receipt and packaging until you have confirmed correct operation.
