Hey all, I've got about a 5000 gal pond. I have 2 Laguna pumps, one up to my waterfall, the other I added on to another filter, question, can I run the 2 pumps into the main line to my waterfall. In other words, can the smaller pump hose connect into the bigger pump where the junction is on the bigger pump?

Can, but I wouldn't. Depends on so many things, pipe size, position of connection, etc... And there's no standard for how so you'd be guessing. You risk water flow doing odd, unexpected things that would reduce flow and/or wear one or both pumps..

Thanks, I appreciate that, I guess I'll just leave my second filter or create another water feature!

2 pumps are always better than one .If one goes out you are not risking your pond and your fish and 2 filters just make it better .Your welcome ,my pond is 5000 gallons

I'll go one step further on the 2 pumps are better theme...on 2 separate circuits. Often when a pump fails a short is created that trips the breaker. If the other pump is on that breaker...it's down too.

But this is needed only for ponds that need pumps to keep fish alive. That generally is only true for Koi ponds with lots of massive fish for the pond size. Virtually every Water Garden and even most Koi ponds are just fine with no pumps. Gas exchange still continues to happen, just not as well. I would not suggest anyone worry and install a second circuit.
