Spa Filter Parts – it’s one of the smaller categories of hot tub parts that we carry, and one of the easiest components of your spa to troubleshoot and repair.
Almost all portable, above ground spas use a cartridge filter set-up, similar to the spa filter assembly shown here to the left. A pipe carries water from the skimmer and or spa drain, into the filter body, where the water is forced to pass through the cartridge before exiting the filter on the opposite side.
However – there are many manufacturers of spa filter assemblies, or complete spa filters. In alphabetical order, we carry spa filter parts for Hayward, Jacuzzi, Rainbow, Sonfarrel, Sta-Rite and Waterway.
The first step to finding the right spa filter part is to know which spa filter assembly you have on your spa.
Which Brand of Spa Filter do you Have?
As mentioned above, there are many manufacturers of spa filters, and even though we carry parts for the most popular brands, there are dozens more. If you have a Jacuzzi brand spa, it’s a good bet that you also have a Jacuzzi brand filter assembly, but with other makes, you can’t be sure without crawling under there and taking a close look.
You should be able to find the name of the filter manufacturer, or at least a part number stamped onto the filter body, or filter lid to help you determine the make of your filter assembly. Your spa owner’s manual may also help point you in the right direction. Still no luck? Take a photo, and email it to us, we’ll be glad to help.
Which Types of Spa Filter Parts do you Need?
1. Skimmer Parts: That’s right, I said skimmer parts, like the mounting plate or gasket, diverters, skimmer baskets, skimmer weirs… on spas, these are considered to be filter parts. Not so for swimming pools, but on spas and hot tubs, skimmers are often connected to the filter, and in some cases, the spa filter sits inside of the skimmer, underneath the basket, in a combination skimmer and filter body.
2. Filter Body: The filter body is often one of the first things to crack due to freeze damage – even a small amount of water left in the bottom of the filter tank can expand and crack the filter body. When this happens, the filter head or top may also crack, or the filter body lock ring – the large nut that tightens the filter lid to the filter body. If your spa filter is leaking around the lock nut, you may need to replace the o-ring for the filter lid. Probably the most common parts we sell for filter bodies is the drain plug, or the air relief plug – these just seem to grow legs, or roll up under the spa, never to be seen again.
3. Filter Guts: Inside your filter body, we have the filter cartridge. Some spa filters also contain inserts or additional parts that are used to seal up the cartridge, to force the water to go through the filter cartridge and not around the filter cartridge. A few spa filters have an internal bypass parts, to allow excess flow to bypass the cartridge. Yours may have internal o-rings, spacer rings or one-way flow check valves, or small filtering screens.
