Pond Aerator Repair

[@KLMPublications]

I should note that in terms of routine maintenance, this would include piston seal replacement as I noted in the video above, but the other, more frequent update should include replacing the air filter as needed. Most models today have a corrugated paper filter which is inexpensive and easy to replace. Doing this regularly will help with the performance and longevity of the pump.

Do the piston rings have an up or down side?

[@klmponds]

Yes, both the piston ring and the piston cup would need to be oriented properly...up and down sides are different. The easiest way to get this right is to pay attention when you take the pump apart initially...assuming you are repairing it for the first time, they'll have it right from the factory. Depending on the brand you are working with most will have decent instructions to work with too.

Where do I put the replacement filter

[@klmponds]

Sorry, missed your question...there is a black canister attached to the pump...the replacement filter goes in that. Its probably removed from the pump in this video...it would go on one of the intake or "in" ports. The other intake port would be plugged.

what type of capacitor do you use for that pump?

[@klmponds]

Hi Brandon. It depends a bit on the brand from what I can see...but as a general rule...the 1/4 HP, and the 1/2 HP which you see in this video are using a cap that indicates 370VAC/B 50/60Hz on the label. Hope this helps for you.

Where to get repair kits?

[@klmponds]

It would depend on the pump model. Let me know on the brand and model number and I can give you more information.

If I got the code right, this is coming up as a Vevor pump...a chinese import. If vevor doesn't have the rebuild kit, I'm not sure who would. There were pumps early on they sold that did not have kits...not sure if this is one of them or not. Just curious...how long have you been running the pump? A fair number of people had theirs crap out pretty early on, some caught fire, etc. That's the word on the street at least.

[@klmponds]

There is a reply on the page for that pump, at the bottom...someone asked about rebuild kits and as of spring of 2024, they said they don't sell parts separately. They'll replace the pump within 12 months but after that, you may be out of luck.
