I also do not run my skimmer 24/7 I run it 12/12 which means that the 2500
gets turned on/off every 12 hours. I guess I'm just lucky.

Actually I took my original Rio 2500, ground down the raised area where

the

plastic was injected and it has lasted longer than it did with it's
first
impeller. I think it is a quality control problem.

I wonder if it is not a problem with the 2500 model. I have three
smaller Rio pumps on my skimmer, refugium and my water top off system
and they never have problems.

The Rio 2500s that I have had seem to be failing in the same way. The
impeller seems to get worn on the side towards the motor, and the only
thing I can see that could cause it is a small raised area where the
plastic was injected into the mold.

It looks as if the impeller gets too much play and jams in the

housing.

Two pumps in three months is too many, I am going to try a Mag 7 next.




I actually just pulled out a Mag 7 and put the Rio 2500 back in. The

Mag

was less than 2 years old and had reached the point (about a year ago)

where

every time it stopped, I had to tear it apart and clean it to get it to
restart. It also seems to me that the Mags dump way too much heat into


the

water. Since this is my main return pump from my sump, failure is not

an

option. I just ordered an Eheim last night. My experience is that Rio

2500

and 3100 are decent pumps (for what they cost), the 1700 and 2100 seem

to

be

the trouble makers that have given Rio such a bad reputation. I still

have

a Mag 9.5 running my skimmer after several years, and it has run pretty

much

24/7 without a problem. Don't underestimate luck when it comes to

pumps!

I've been through a couple 2500s this year with pretty much the same
outcomes as you have mentioned. Currently using Pondmasters until Rio
sort out their quality assurance problems.
