Can I Terminate a Lease Because the Landlord Failed to Provide Running Water on Several Occasions for as Long as 48 Hrs?

In Rhode Island you should start with a call to the Building Inspector for your community. They will immediately investigate and issue a citation to the Landlord. Once the Landlord has been cited, especially if they have been cited on more than one occasion, most Rhode Island Judges will not enforce the remainder of the lease agreement against you. The important part is that your give your Landlord notice of your intent to vacate and the reason why. Thirty days should be enough.
