New pipe update
After a lot of consideraton and just being lazy we took a trip down to Harbor Freight and picked up an inspection camera for less than $100.00, we were able to get way under and behind things to see what was there.
With the camera we were able to see from the shower acces hole on the outside to the floor exit to the rear, and where the tubing drops down in the front.
By using a fiberglass fish wire assisted by running it inside a hose, we were able to get the fish from the bedroom behnd the shower, down to the area along side the bathroom and almost to the back of the icemaker, the camera has a hook attachment that we were able to use to catch the fish.
We added loops of rope so we had a continous loop to allow for multiple pulls.
We got from the shower faucet to the bedroom and the bathroom sink to the front.
All connections are in access areas so further repairs will be easy if needed, it took a 100 ft chunk of PEX tubing and a bunch of fittings and a few hours of time, but all tubing is now PEX and no cabinets or appliances were moved or altered to get it done.
So if anyone else discovers their gray PB fittings starting to leak, get a camera and start exploring your options, the repair is just another challange.
