Had the device about 6 months. Works great, clean it every week. About 2 weeks ago started making a grinding noise. Removed pump and tried it and very quiet. Cleaned all parts of the pump throughout and reassembled it. Same noise but still moves water. Not sure what to do, just don't feel like putting out another $20 for another motor.
Thanks for sharing your experience with the Drinkwell® Big Dog Fountain, Danny! We are sorry to hear that it is noisy. We may have a quick fix for you. While the pump is taken apart for regular cleaning, put a drop of veggie oil or olive oil on the pin inside of the pump to lubricate. This can make a huge difference! Please also know that this fountain carries a 1 year warranty. Please give us a call at 1-800-732-2677 for troubleshooting and warranty needs.
Purchased one about 5-6 years ago and still works fine.
Same pump and impeller, runs 24x7 inside.
And, I'm not fiddling with it very often beyond simple cleaning - soap-less but very hot water.
Tried some dishwashing liquid on it once and made quite a mess.
Broke one of the clips off the riser taking it apart very early on.
Getting a second to move out to a covered patio area to replace an unfiltered system.
I purchased our Big Dog fountain over a year ago, and it has run night and day for the entire time. I came home from work and the unit was making a horrible noise. After a bit of searching I realized the pump can be removed and cleaned. Now the pump is clean, quiet, and working flawlessly. Our dog and four cats thank you for a great product!
