All of the bladder tanks I've come across have failed bladders, my trip to the landfill this morning there was a water softer tank that had froze and split the casing. Often find discarded submersibles.
At the ranch had a 10 hp submersible used for irrigation, I had installed under ground PVC with hydrants 300 ft apart. The irrigation wheel held 900 ft o line a water turbine would reel the line back to the wheel when the canon made contact with a push bar the water would shut down raising the pressure.
The rise in pressure detected by the pressure switch at the pump house would turn the pump off, no bladder tank on the irrigation system.
I had also installed a submersible in the same well below the large 10 hp for domestic water, before that we were getting our water from a creek via gravity feed but our new born did not take kindly to this water supply from the creek.
Ranch had two water licenses, one on a river located across the main road and the creek above the property, gravity feed from the creek only required moving the aluminum pipes and clearing out minnows from the sprinkler heads.
Do I miss the ranch, No. It was too small to earn a decent living plus we had more horse than cattle.
A plumbing company would all on me when they had a work overload, one day got a call customer had no water. Water table had dropped below to what a single line pump could draw. Customers pump was convertible, just need to add a few parts.
This turned out the be the most miserable pump to get primed, keeping my words of disgust silent after a couple o hours finally had the pump primed. A week later the customer showed up at my shop giving me a brand new pipe wrench and a sears gift certificate, asked him what this was for and he replied it was for my conduct on the job.
On another pump install, new pump - customer is happy to have water.
A week later the outfit feeding me these odd jobs calls me up, when I arrive at their shop the counter guy is kinda nasty with me saying the pump had quit and that I would be replacing it free of labour costs.
No problem, I grab a new pump and get it installed, when I have a look at the pump just removed discover a slug had entered through the cooling vents at the rear of the motor.
Motor must have been in the off position when the slug entered, anyhow when the pump motor started with the slug in there the centrifugal start switch could not function as it should have. So the start winding's could not disengage.
When I get back to the plumbing shop told Terry to stuff it where the sun don't shine.
Was a good gig while it lasted, they paid me a rate well above an hourly wage.
The awesome part is the responsibility of keeping the pump motor free of trash including slugs would have been the customers duty.
