Repair Wait Long Period to comprehend for tenant

[Frances L.]

The tenant called for the water heater repair on Wed afternoon, the repair man went to examine the water heater next day morning. He ordered the parts and parts will be in Tuesday. It takes really long time to fix. It caused the inconvenience for the tenant. Right now the tenant stated by law, she would not pay for the rent for the days without the water heater .The property is in PA. I am wondering what the law in PA for this issues . I know unemployment has one week waiting period etc. Insurance has some deduction according to the policy. I do not know what is those reasonable comprehend for the tenant. Thanks.
