Doerr 1/2 HP electric motor. Replacement Cost?

Dag-Nabbit! I don't have a clue about cost.

-- The thing is, when I don't know what the problem is, I do a lot of experimentation...

Are you sure that is the model? There is a Doerr LR22132 new on eBay for $95.00

Yep that's what I was gonna ask too. If that Z is really a 2, there are lots of hits on google for Doerr LR22132 However it appears to be a 3/4hp motor.

I'm sorry, I can't answer your question, but it raised a different question in my mind. We have a small 3 year old home with a new 900 gallon septic system. There are only two residents in the home. The system has no pump, nor do any of our neighbors' systems, AFAIK. At what point does one need such a pump in a system? Is it based on size, type of soil, or other factors? If it makes any difference, we live in the AZ desert with typical desert soil and no freezing temperatures.

TIA

True! Probably not the same motor. Emerson bought Doerr a few years ago.

What is important is the "Fr J56Z" That is the frame, any motor with that frame will physically bolt in as a replacement, just match the volts & RPM.

It has been my experience that if the problem is not a start or run cap, then it is usually cheaper to just replace the smaller motors.

The Emerson site is a place to look for motors. At least recent years ago for me...replacing a pool pump motor.

There are two different approaches to residential septic systems. The simplest and more common system by far, which you have, relies on bacteria that don't need oxygen. The OP has one that relies on bacteria that need oxygen to work and break down the sewage, hence the need for the aerator.

I'm not sure what the relative tradeoffs are, but I think one is that with the latter system, the effluent is cleaner, the leach field can be smaller, etc. So, for some applications it can be a good fit.

To Mr. Boatwright:

Your system should be fine unless Arizona goes under water. The non- aerating (sp?) systems are most common. The only caveat is to never flush anything that will not decompose. Examples are paper with lots of clay, such as magazines and some high-end paper, and metals, and sand and dirt and things that you would not put into a compost pile. Toilet paper that says it is safe for septic systems is preferred. If you are reasonably careful, you should have the holding tanks pumped out every 4-5 years to make sure nothing gets out into the drain field that could clog the field tiles/plastic pipes.
