We have a tenant that wants her hot water to be hotter. I have heard that some other landlords have had their tenants sign a waiver or release of liability before they will increase the temperature of the hot water, since there is a risk of scalding if only the hot water in the sink is turned on. I was wondering if anyone has heard of this, or has used a waiver like this. I have searched the internet but haven't found anything similar. Thanks!
