We're glad to know you enjoyed staying at our home, and we are delighted to host you. However, there is a small price we all have to to pay by living in California. Our government is very concerned about preserving our environment. Low pressure toilet and shower as well as tankless heater are just a few of our building codes that try to preserve water and our beautiful land. Because we are also required by the California Building Codes to install tankless water heater as part of our remodeling, our hot water needs a few minutes to come to faucets and shower head. I agree that we need to put a note in our guest binder, so that our guests will be aware of the situation. We certainly appreciate our guests like you to continue helping us to make our home even better. Thank you very much for your comments and feedback!
