subport under the houes basement or cawl space sound wrong, spacing for bracing 12 foot spand is code missouri. the bouncing you typed about let's know the space is wrong.
4x6 for lifting is ok but the piers in the picture are a over kill, and stack without a bace. The way they are know will sink you will need a solid block. wee use trailer pad 16x16x4 with rebar. If you raising the house just on one side you tpyed nothing about the seal plate.
Brace and brace somemore if joists are level why not put the floor down just for keeping square and don"t for get the BRACE. Just how high do you have to go and is this 1 story or 2 let us know.
In some cases the water line run just under the floor but most are under the slab Our hot water went first then about 3 years later the cold. We have run all the plumbing over through the attic and down the wall to were there needed. We used the PEX plumbing .
you can have water lick under the slab and not have water come up cause it is gone down in the ground Turn off the hot water at hot water heater and look at your water meter hot water pipes deterate under slap sooner Now you get to cut up the floors and or run pipes over head. moisture meter...
What is missing here is nobody said anything about if your putting down tile, with the weight added you need to check the bracing under the floor. To wide of spand will bouce and stap the tile.

you need to start at the end of your main beam make sure the beam is in level with the seal plate take your 4 foot level go from one end and other end of the house raising piers as you need . using oak shims never use steel plates they draw moisture.
