Monarch effluent pump rebuild

[Tracs]

I have a Monarch BE-S33 self priming effluent pump in my basement, in one of the bedroom closets. It pumps the liquids from the sewage tank out to the leech field. Or that is what I believe. I have only lived here for 6 months.

The pump is squeaking/chirping when running. I would think it is the electric motor bearings. I don't want to come home one day and find a seized pump and backed up sewage system.

I have rebuilt electric motors and swimming pool pumps before. Some have more challenge than others.

My main question is how much grey water is going to come out of the pump when I start to disassemble it and the hoses? I don't really want that spilling into the basement closet. Is there a way to get the electric motor off the pump without spilling liquid everywhere?

Second, with this pump looking to be ancient, what are the chances of the long motor case bolts coming out without snapping. I've had that problem with pool pump motors.

The parts diagram doesn't break down the electric motor parts, but I have a few good shops in town for parts. I would take the whole thing for a rebuild but cannot be without the pump for more than a few hours.

Thoughts on rebuilt/replacement?

A new pump is $500

Hmm, that pump has lived a long life by the looks of it. Are there any date codes on the pump or motor?

I think you are very wise to proactively take care of it, but personally I am not a huge fan of DIY sewer work!

If I am going to go to the trouble of removing this thing, I would replace it. I don't think there is anyway to do this without having it be a sh^&ty job, so I really would hate to have to do it twice.

What is the level of the tank and field in relation to the pump?

I think I'd be inclined to bite the bullet and replace it myself anyway.
A full house is never a good thing in the plumbing world.

hard to know how much water will run out when you disconnect it .
also, if you run into problems with repairing, do you have a back up plan?
terrible time to have to run out & buy a new pump and re plumb etc. just then is one someone in the family comes down with a bad case of diarrhea .
it is probably a simple fix, but... a new motor probably is a good idea .

If you slide the pump to the left a little, you’d have room for some block valves so next time won’t be as crappy.

The field is downhill quite a bit. The tank on the other hand is a guess.. I wouldn't think it's level is above the pump because I think if it was then the main drain wouldn't work on just gravity. If my thinking makes sense

I think I'm gonna get a complete replacement pump the have on standby

That's a good idea.
