I have a 50+ year old ranch house with a 3/4" copper main supply coming out the slab. It has a sweated gate valve about 5" above slab and then a sweated pressure regulator in-line with 3/4" main line for the rest of the house. The gate valve does not fully shut off (steady dribble) when closed and city water shut-off *almost* complete shuts off when turn if off at the meter. It has very slow drip (~1 drip every 2-3 seconds) matter how tight I close the value at the street. Normally this has not been a issue, since I can open a tap in the basement and away from where I'm working and have no drip to contend with.I have a 1” PE line coming off the old well into the house through the stone wall. After it comes through the stone wall, a 90* fitting (plastic) connected the PE lines and from there it was buried under the dirt floor and travels to the house plumbing. I cut the PE line about 20” after the 90* fitting and put an adapter at the end to transition to PVC and then to the house plumbing. One night I came home from work at 2AM and there was no water pressure. I went into the basement to find water all over the floor (dirt plus water equals mud) and shelving. The 90* fitting had blown out of the horizontal line coming into the house and had blown water across the basement. THANKFULLY, I had used a pressure switch with a low-pressure cutoff, so the pump shut off. The contents of the two water tanks were pushed out against the stone wall and then flooded the floor. This could have been catastrophic, but we were lucky.
I want to make sure that this doesn’t happen again. If the fitting had only leaked, and not blown out, the pump would have continuously pumped water in the basement, and this would have been catastrophic. I have seen products that shut a valve if a sensor detects water, but my thought is that they would burn the pump up. I want a system that will kill the electrical supply to the pump if a sensor detects water.
Do you have any recommendations for me? The only option that I have found is this Lifera Plumbing
As always, I appreciate any help.

Since this is the main supply line, with the slow drip from the street, I'm concerned that I may not be able to get enough of the water out of the supply pipe to sweat on a new connector before it fills up again. I sweated a bunch of 1/2" copper over years and with no issue... but always with a supply line I could complete shut off.
So I'm thinking of just cutting out the gate valve and pressure reg, clean up the Cu pipe and install the 3/4" FIP compression fitting on the supply coming out of the floor, being careful on tightening to not mess up the supply piping. Once that's done, just add the ball valve and new pressure reg call it done.
That said, I've used 3/8" and 1/2" compression fittings a bunch but never a 3/4". So any wisdom and advice is appreciated.
