How do I know which replacement part fits my pump, filter, or UV clarifier?

Check the model number or wattage printed on the equipment itself before ordering. Parts in this category are built to specific pump series, filter models, and UV clarifier wattages, and a part that looks similar often won't fit or perform correctly. If you can't find the model number, our team can help identify it from a photo.

Do I need to replace my UV bulb every year even if it still lights up?

Yes. A UV bulb keeps producing visible light well after its effective UV output has dropped, so appearance isn't a reliable way to judge whether it's still doing its job. Most manufacturers recommend annual replacement regardless of how the bulb looks.

What's the difference between a UV transformer and a UV bulb or sleeve?

The transformer supplies power to the UV bulb and is the part most likely to fail from electrical wear or moisture over time. The quartz sleeve is the glass tube that separates the bulb from pond water, and it can cloud or crack independently of the bulb or transformer. All three are sold separately because they fail on different schedules.

Can I use a universal or generic impeller instead of the model-specific one?

It isn't recommended. Impellers are sized to a pump's magnet housing and flow rating, and a generic substitute that doesn't match those specs can run inefficiently or damage the pump motor. Match the impeller to the pump series it's listed for.

What's included in the PondMAX Replacement Annual Service Kit?

It bundles the wear parts a PondMAX pressurized filter typically needs replaced on a yearly service schedule into a single order, rather than buying each seal or component separately. Check the product page for the exact contents before ordering, since kit contents can be updated by the manufacturer.

Why is water flowing backward through my check valve when the pump is off?

A check valve that's stuck open or worn out will let water siphon backward through the plumbing once the pump shuts off, which can drain a waterfall or upper basin overnight. Replacing the valve assembly, such as the Aquascape 2 Inch Dual Union Check Valve Assembly, usually resolves it.

How long do special order parts take to arrive?

Special order items, like the Sequence PurFlo Basket Strainer or the Americo filter media roll, take longer than in-stock parts because they're ordered from the manufacturer after your purchase. Lead times vary by brand and season, so contact us directly for a current estimate before you're relying on the part for an urgent repair.

Do you carry replacement parts for equipment I didn't buy from Puget Sound Ponds?

Yes. Most parts in this category are sold by model or brand, not tied to where the original equipment was purchased. As long as your pump, filter, or UV clarifier matches the model the part is listed for, it will work regardless of where you bought the original unit.

Replacement Parts

Puget Sound Ponds carries replacement parts for the pumps, filters, skimmers, and UV clarifiers already installed in Pacific Northwest ponds. This replacement parts section covers impellers, UV transformers and quartz sleeves, filter media, o-ring and service kits, pump covers, check valves, quick-connect fittings, and fountain nozzles from brands including Savio, PondMAX, Teton, Aqua Ultraviolet, PerformancePro, Atlantic, Oase, and PondMaster.

Most of what wears out on a pond system is small and specific to one model. A skimmer filter needs a fresh pad or lid gasket. A UV clarifier needs a new transformer or quartz sleeve once light output drops. A magnetic drive pump needs a replacement impeller after a few seasons of running grit through it. Rather than replacing the whole unit, these parts let you fix the piece that actually failed.

If you're not sure which part matches your equipment, check the model number stamped on the unit before ordering, or give our team a call. Buying the wrong impeller size or transformer wattage is the most common mistake pond owners make when shopping parts on their own.

What Belongs in the Replacement Parts Category

This category exists for one reason. Pond equipment wears out in specific places, and most owners don't need to replace the whole unit when that happens.

A pressurized filter that's been running for three years usually still has a good pump. What's failed is an o-ring seal, or the UV bulb has dropped below effective output. A skimmer that clogs every week might just need a new filter pad or lid. These are the parts stocked here: impellers, UV transformers, quartz sleeves, o-ring and service kits, pump covers, filter media, check valves, fountain nozzles, and fittings for the pumps, filters, skimmers, and UV clarifiers already installed in most Pacific Northwest ponds.

None of these parts are a universal fit. Each one is built for a specific pump series, filter model, or UV clarifier line. That's the point of buying a replacement part instead of a generic substitute: it's made to the tolerances of the equipment it's replacing.

Replacement Parts by System

Pump Parts: Impellers and Fittings

The impeller is the part inside a magnetic drive pump that actually moves water. It's also the part that wears fastest, especially in ponds with sand, grit, or heavy debris load. The Atlantic Replacement Impellers for MD Series Pumps cover that exact failure point for Atlantic's MD line.

External pumps need different parts. The PerformancePro Quick Connect Fittings for Artesian2 & ArtesianPro Pumps replace the union fittings that connect the pump to plumbing, usually the first thing to crack or wear a seal after a few winters outdoors. A PerformancePro ProTect Pump Cover MPC-10 protects an external pump housing from weather and UV exposure, which matters more than most owners realize since sun-damaged plastic housings are a common reason pumps fail early. For anyone running a pump in brackish or salt-supplemented water, the PerformancePro Salt Water Kit - Add on swaps in the seals and components rated for that environment.

UV Clarifier Parts: Transformers and Sleeves

UV clarifiers have two parts that wear out on a schedule rather than from damage. The bulb loses effective UV output long before it visibly dims, and manufacturers generally recommend replacing it annually regardless of how it looks. The quartz sleeve that houses the bulb can also cloud or crack over time, which blocks UV light from reaching the water even with a fresh bulb inside.

Puget Sound Ponds stocks transformer assemblies for several UV clarifier lines. The Teton Replacement UV Transformer Assembly is built for Teton XUV Clarifiers specifically, and the PondMAX Replacement UV Transformer serves PondMAX's pressurized filter line. For Aqua Ultraviolet's Classic series, the Aqua Ultraviolet Replacement In-line UV Transformers come in 15, 25, 40, and 57 watt versions to match different clarifier sizes, and the Aqua Ultraviolet - Classic Quartz Sleeves with Rubber Seal replace the sleeve itself. PondMaster owners can find sleeve replacements sized for 10, 20, and 40 watt units in the PondMaster - UV Clarifier Replacement Sleeve.

Filter and Skimmer Parts

Skimmers and pressurized filters both rely on seals, pads, and small hardware that fail well before the housing does. The Savio Standard SkimmerFilter Replacement Parts and Savio Compact SkimmerFilter Replacement Parts cover the two most common Savio skimmer sizes.

For pressurized bead and media filters, the PondMAX Repl. O-Ring Kit (For PondMAX Pressurized Filters) replaces the seals that keep the filter housing from leaking under pressure, and the PondMAX Replacement Annual Service Kit bundles the parts most filters need replaced once a year into one order instead of several. The Sequence PurFlo Basket Strainer is a special order item for Sequence's PurFlo system. Filter media wears out too. Americo Filter Media Coarse Density 'Black' comes as a special order roll for anyone rebuilding filter pad stacks rather than buying pre-cut pads.

Vacuum, Plumbing, and Fountain Accessory Parts

A few parts don't fit neatly into pump, filter, or UV. Pond vacuums have their own wear parts, and the Matala Power Cyclone Vacuum Replacement Parts cover the hoses, seals, and fittings specific to that vacuum model.

Plumbing hardware wears differently than mechanical parts. It cracks from freeze-thaw cycles or UV exposure rather than mechanical friction. The Aquascape 2 Inch Dual Union Check Valve Assembly replaces a check valve that's stuck open or closed, which usually shows up as water flowing backward through a waterfall pump once it's shut off. The Atlantic Foam Gun Applicator is for waterfall or spillway construction work with expanding foam, not a repair part in the usual sense.

Fountain owners have their own parts to watch. Nozzles clog, corrode, or get knocked loose, and each style throws a different spray pattern. Puget Sound Ponds carries several Oase nozzle styles, including the Oase Schaumsprudler Professional Nozzles, the Oase Grand Vulcan 43-3 Silver Professional Fountain Nozzle, and the Oase Lava Professional Nozzles, each producing a different fountain effect.

How to Choose the Right Replacement Part

Match the Part to the Exact Model, Not Just the Brand

Buying by brand alone is the most common mistake in this category. A Savio Standard SkimmerFilter part won't fit a Savio Compact SkimmerFilter, and a 25 watt Aqua Ultraviolet transformer won't run a 40 watt unit correctly. Before ordering, check the model number or wattage stamped on the equipment itself, not just what you remember buying it as. If a part listing shows a wattage range or model series, the equipment needs to fall inside that range for the part to work.

Decide Between a Single Part and a Kit

Some failures call for one specific part. A cracked quartz sleeve or a torn impeller is a single-part fix. Other situations call for a kit. The PondMAX Replacement Annual Service Kit exists because several wear parts on a pressurized filter tend to fail around the same interval, so replacing them together saves a second order a few months later. For a first-time filter or UV clarifier service, a kit is usually the more practical starting point over guessing which individual seal has failed.

Consider Lead Time on Special Order Parts

A handful of items in this category, including the Sequence PurFlo Basket Strainer and the Americo Filter Media Coarse Density 'Black' roll, are special order rather than stocked. Special order parts take longer to arrive, so it's worth ordering ahead of a scheduled maintenance visit or the start of the season rather than waiting until a part fails.

Seasonal Timing for Pond Parts

UV bulbs and transformers see the heaviest use through spring and summer, when algae pressure is highest and clarifiers run longer hours. Checking UV output and quartz sleeve condition before the growing season starts is worth the ten minutes it takes.

Pump and plumbing parts tend to fail after winter, not during it. Freeze-thaw cycles stress check valves, fittings, and seals even in pumps that were pulled from the pond for the season, so a spring inspection before restarting equipment catches most of what's about to fail before it turns into a bigger problem.
