Frequently Asked Questions

Is the 356879Z a genuine Pentair part?

Yes. The 356879Z is a Pentair part supplied under that manufacturer part number. It is not a generic substitute.

How do I choose the right horsepower?

Match the horsepower and service factor to your existing pump, and check that your filter's design flow rate can handle it. An oversized pump pushes water through the filter too fast and reduces filtration quality.

Is a variable speed pump worth it?

Variable speed pumps typically cut pump energy use by 50 to 80 percent versus single speed, because running longer at low RPM moves the same water for far less power. Several US states now mandate them for replacements above a certain horsepower.

Will this pump fit my existing plumbing?

Check the suction and discharge port sizes and the distance between the pump's mounting feet. Union fittings on most modern pumps allow some adjustment, but a different footprint may need re-plumbing.

Does California Title 20 affect which pump I can buy?

California restricts the sale of single speed replacement pumps above 1 total horsepower, so most residential replacements there must be variable speed. Similar rules apply in several other states.

How do I confirm this part fits my equipment?

Check the part number stamped on the component you are replacing, or find it on the parts schematic in your owner's manual. If the number differs or is unreadable, send us your equipment model and serial number and we will verify fitment before you order.

How quickly does this ship?

In-stock items ship from our US warehouse on business days. You will receive tracking by email once the order leaves the warehouse.

Can I return it if I ordered the wrong part?

Unopened, uninstalled items can be returned within 30 days. Equipment that has been installed or plumbed cannot be returned, so confirm fitment before installation.

Is this covered by a warranty?

Manufacturer warranty terms vary by brand and product. Warranty claims generally require proof of purchase and, on installed equipment, evidence of professional installation.
