      Replace old pump or repair it?

      I have an old Evolution ESM2500 thats been running for about 3 years, and lately it hasnt been flowing as strong as it used too. And today I barley had any water coming out of my water fall. I was hearing something rattling around today in the pump, when I poked around in it, it felt like the impeller or something else had either broken or got loose. So my question is it worth fixing and if so how? Or should I buy a new one, if I were to go this route what would you guys recommend. My pond is a little over 900g, my pump sits above the water line so it pulls the water up and over my S/G filter. So Iam guessing it needs at least 4' of head. Hopefully this info will help. Thanks in advance!

      Are you sure it's the pump? Where does the pump pull water from and could that be restricted?
      I have several different sized Evolution ES pumps and they're pretty easy to take apart. Before I
      just replaced it I'd take the screws out and take a look to see if you can see what the rattling is and/or
      if anything is broken.

      Thanks for the reply. It pulls through a retro bottom drain, good idea on the possible clog, never thought of that. The reason why I think something may have broken in there and I forgot to add in the original post, was when I was feeling around in the pump I pulled out this broken plastic piece looked kinda like a thin bushing or perhaps a washer. Do you know where I could find parts for this pump?

      If you've got the cash, you might consider going ahead and replacing it and then repair the old one as a backup.

      Evolution advertises here on the forum; look for their banner at the top of the forum!
      Here's a link to their online parts... I think if you give them a call they could point you in the right direction:

      Being in Florida there are probably dozens of pool shops nearby that could steer you to a local pump repair shop
      if you don't want to try and do it yourself.

      Awesome thanks guys, that was the idea I was leaning towards, since I like to tinker. Id probably get a new one and have the old one as a back up. Got any recommendations for a new one? Something simaler to the one I had or something a little bit stronger.

      I’d recommend that you look into the Periha pump model 14k/18k
      Or a iron might that rate 2400 gph
      These are affordable brands but you can also go for sequence, performance pro etc if you have the budget

      Are you also using a priming pot with basket before the pump?

      So I was looking into the Iron might you guys recommended and found something close to what I was using, but the only difference is the Iron might is a 1/15th HP vs my 1/8 old evolution. Will that make a difference in my set up?

      Pump motors either run full speed or not at all. So if the motor is running your problem is most likely a clog some where. The impeller vanes on the 2500 have a fairly small gap and can be prone to plugging with algae. Remove the face plate, and check the impeller, it unscrews counter clockwise. If not the pump you have a piping problem. k

      Interesting didnt know that, Ill def have to look into that. Didnt know they were that easy to take apart. Unfortunately I still need something even if its temporary to keep the system running, kinda leaning towards the iron might or maybe a new evolution. Havnt been able to find much info on the iron might unfortunately.

      These guys were pretty good about answering Iron Might questions:

      SpaCare.com
      help@spacare.com

      I asked a question about the difference between the black pump body Waterway Iron Might pumps sold for ponds and the yellow pump body version sold for Spas.

      Typically these are ODP open drip proof motors. They need more protection than a closed type and should be in a dry and clean environment to get long life. This is how they keep the cost lower. Still a good pump and motor but it needs more protection.

      I like the "yellow"... but do not want the 220V.

      I am thinking about getting a 110v one for a backup pump.

      Yeah I was wanting one as a back up one as well, luckily my pond has an enclosure for everything including the pump so Iam covered there. The only thing is do they have one with 2" inlet and outlets? I was wanting to swap out my evolution one for the iron might temporarily, and was wondering if my plumbing could handle the restriction to the pump.
