TTP, removing broke PVC pipe that is glued into a cast iron pump

[GON]

Common issue, PVC pipe glued in place and broken into a metal pump.

Easiest method I know is to take the pump outside, apply propane (PVC will burn), heat the PVC up nice, and use a device to remove the now pliable PVC.

Takes just a minute to do this .I had a like issue 15 years ago and drilled out the PVC. This works way faster and cheaper.

That or a sawzall will do the trick quickly.

PVC fumes are nasty toxic. Most any open bladed saw (or just a hacksaw blade) and done

LOL...you sure seem to be dealing with a lot of broken pipes and stubs lately!

Won't a sazall scar the threading in the metal pump?

Fifteen years ago I installed a ejector pump for water softener discharge. Purchased the best pump I could find as the pump would be sitting in salted water 24x7.

Purchased two pumps, one as a spare. Both pumps were purchased by another person from Amazon and returned. I purchased the two pumps from a Amazon skid buyer, paid about ten cents on the dollar.

I only repaired (removed the broken PVC) from one of the cast iron pumps, not the spare. These pumps were returned to Amazon because the broken PVC, not able to handle shipping.

After moving this heavy pump across the nation multiple times, I finally have a use for it. I need to pump the water out of our in the ground pool.

The pool's water is full of years of calcium. Research indicates the only way to remove the calcium is to remove the water, and refill the pool.

I have a dedicated water softener to refill the pool, in hopes of a significant calcium reduction.

The issue I have no is the discharge water. I am about 200 feet from the street. The pump's discharge opening is 2 and a quarter inches. I am afraid if I step down to a 5/8 garden hose it might stress out the pump.

It definitely could. I've also had smaller diameter pipes break off like that where all I had on hand is a hacksaw blade to cut a notch and pry out the broken off threaded part.

Maybe go to the fire department and see if they have old hose you could have or buy?

You can rent discharge hoses in many diameters.

You only have to cut partway through in order to weaken the pipe enough to manipulate it easier. Even if you did, if that's a sump pump, who cares ? It might leak in the sump but the plastic threads will thread into it fine.

It might leak in the sump

Indeed, the instructions for many sump pumps say to make a small hole (intentional leak) in the discharge pipe just above the pump so it doesn't get air bound.

Surely glad my Wife never hired you as a handyman.

Cut threads on a pipe that is to be reused? Instead of a one-minute no damage method with near zero risk?

The pipe is never "glued in." It may have PTFE tape or non-hardening "pipe dope" compound on the interface to the metal. Cut slot(s) from inside through the broken plastic, almost to the metal, then pry it out and remove. This is a standard technique. Since you are already resolved to do it otherwise, why keep posting?
