Major water leak under bath- maybe rodent damage?

[rvinarizona]

I have a 2016 Forest River WildcattMaxx mode 24RG which had been sitting all summer. Just tested everything ie., water heater, a/c etc and everything looked fine, so turned off water and electric. Went back 2 days later and turned water on and a puddle was leaking from the inspection cover behind tub. Turned water off and removed cover and found rodent droppings inside cover. Turned water on again and from the outside it sounded like a tank was filling (which it was not). Looks like it was the space between the bathtub and underbelly as water was dripping from floor.

Suspect rodent had bitten thru supply lines maybe under tub!


Question is how should I go about tackling this as the underbelly looks pretty permanent. Should I be removing bath tub as, at this point, not sure where water lines are placed.



Unusual problem, so would appreciate any advice I can get

Thanks

Water hose wasn't connected to Black Tank Flush by chance
"Turned water on again and from the outside it sounded like a tank was filling"
***Does it have flush system???

Otherwise.....accessing the damaged line would require removing underbelly cover or cutting a 3 sided window in cover under the area where lines to shower are
**Much easier then shower removal

Underbelly was full of water from when I hooked up water under pressure for couple of minutes. A large nest was on top of underbelly complete with old mesquite pods, cholla and other rat favorite building materials. A small hole was found in one of the nylon 1/2" braided lines leading to tub faucet. This was repaired and water turned on and tanks filled. 48hrs later - no leaking.



Problem is getting rid of rat, which had obviously been there for a while, before just now, biting the water line. electric wire had also been broken.
Put a large rat spring trap close to air vent which had been chewed up. Next morning peanut butter bait had been removed without setting off trap. I replaced bait and following morning trap was upside down with some of the bait intact still. Obvious after that rat will not be going near that or similar traps as must have had a shock when it went off. There were no fresh droppings found this morning. so has it moved house or just lying low for a while before returning?



What to do now is the question. Do not want to put poison down in case rat dies in heater vents. Any ideas, anyone?
