Rated 4 out of 5 by from really good pump I purchased this pump sometime back and have used it in out of the ordinary ways. I originally bought to operate on a small koi pond and it performed well. Since had went to a much larger pond, so this pump was put asdie. It has since been used to pump out my vortex filters, drain my lotus pond when needed, as well as pump dirty water from in ground holes. This little pump finally broke some cover pieces and I currently need it. I emailed to purchase parts and found I can not do so, but can be sent to me under warranty. They never questioned me on purchase date(which I am quite sure was outside the warranty period) , but opted to send me the parts. I will now put this pump back into action and see how much more it will work. I only wish they would sell parts as I know in the future I will need more. I think this pump will last a long time. 4&1/2 stars. It could be a little more energy efficient.

I purchased a 1200 for a 3' tall water fountain.  We used 1 1/4 tubing.  The flow is too hard.  How do you reduce the the flow?

Asked by: Carole Coffelt 1
Hi Carole! We suggest adding a ball valve after your pump that will allow you to reduce the flow. You can also tee the output so that some of it drains back into the pond or use it for another water feature.

My 6 year-old @26586 is humming when I plug it in but there is no water flowing from the filter to the outfall. Is it possible that the pump is filled with silt? I have tried lowering the filter sideways into the pond in case of an air bubble.

Asked by: Tommyd
Hi Tommyd. It sounds like your impeller needs a thorough cleaning. Simply remove the impeller cover and impeller and clean it well with distilled white vinegar and a q-tip or other small cleaning device. We are happy to walk you through this over the phone at 1-800-526-0650.

We want to build a water fall in the back yard. I would like to know what size pump I need if it's just going to pump water from the "sump" to the top where the water fall starts. It will need to go 5'-6' horizontally and 5'-6' vertically. 

Asked by: Go Bucks
Wow, that's a big waterfall! If you want it to be 5-6 feet wide at the weir, your pump will need to move a minimum of 5000 gph at the top of the falls. So it will most likely need to be 6000 - 7000 gph total. BREX

Where can I find couplers for pumps and filter hook ups. I have your pond pump 12000 and can not find the parts shown in your instructions. Your instructions for attaching submersible filters references the parts as 4 and 2. I have no way of obtaining

Asked by: Joe99
We do not make a pump that is rated at 12000 or a model 12000 pond pump. Assuming you mean the WGP 1200, I believe you need the hose inlet adapter and the prefilter adapter. Please email us more information on what you own, perhaps pics even. techsupport.tetra-fish@spectrumbrands.com. BREX

I purchased the Tetra Pond  debris handling pump.  The adaptor goes from 1.5 to 1.25 inch.   My hose of waterfall line is 1" do you have an adaptor to that size?   Where can I purchase it?   

Asked by: Duke1
No, we do not. You would attach tubing of 1.25" and run it to within a couple of feet of the waterfall, then insert a PVC reducer and reduce the tubing down to 1". Add your two feet of 1" tubing and you are good to go! Reducers are sold in the plumbing department of DIY hardware stores. BREX

I have a one half acre lake what size pump do I need to just aerate it?

Asked by: Dicky Do
You will need one that can move a substantial amount of water, and it depends on the depth of the pond, and what you intend to connect to the pump to do the aerating for you, such as a fountain. Our largest pump is the HCP3600 which moves 3600 gph at a head of 1 foot. BREX

Hi we got the pump and filteboxbefor this weekend. We submirged the filterbox but the pump for the smalest pond is only pumps a few seconds and stops for little while before it starts again. They are suppose to pump constantly? Torill

Asked by: Beginner56
Hi there, Torill. They are supposed to pump constantly. The pump is either defective or underpowered. Check out this article on choosing a pump: http://www.tetra-fish.com/Pond/pond-information-center/pond-building-how-to-choose-a-pump-for-a-pond-waterfall.aspx.
