I would be fascinated to know what his actual medical diagnosis might be because he would work his butt off and had some great ideas in design areas. 

I highly doubt a lawyer will tell them they got a case with out a legit diagnosis 

The standard pet fees and any applicable lease violation fees will apply if Resident(s) are found not to be in compliance with ESA Certification requirements as follows: ESA Certification requires diagnosis from a local mental health professional.

HUD recognizes that some healthcare providers are selling ESA letters over the internet without any real diagnosis. 

This likely will not state the disability, and they are not required to disclose the diagnosis.

Without more info a diagnosis is impossible.FWIW, any tank hot water heater should be set to 140 and have a mixing valve to provide ~115 water.

GeorgeConcerning your vent problem ,,,I do not like Studor vents,,,,I like traditional old fashioned vents that go from the fixture to the roof,,,no matter what it takes to route them up and out thru the roof.I strongly suggest you go to a local plumbing supply house that sell to the trade only and get a reccomendation on a local father and son team with many years experience,that pays their supply house bills on time and have a great reputation.You need a thorough diagnosis of this problemGet a quote and pay these folks and let them work their magicIts hard for me to diagnose your problem with out photos or drawingsIn this case as I suggest find competant local helpBestDD

I utilize Doctors only for diagnosis.

It's really hard to find a company that is good.....and by good I mean they repair any plumbing leaks the cause, they can do minor electrical diagnosis, and things like that.

Once the entire picture is known, a diagnosis can be given.
