I will assume Srylant has done the research and understands what is an acceptable temperature variance and can support breaking the lease after one month by showing the unit rented had water temperatures "unstable" for bathing, making the rental unit uninhabitable.
It's a high hurdle, I think.
I hope s/he is not hoping with the interrogatories to have the landlord prove in his answers what s/he needs to prove (e.g., maintenance request went unanswered, temperature of water was below standard, etc).
The legal professional s/he sees for help with the interrogatory questions could provide Srylant with guidance on the lawsuit.
