Plumbing in the Home/Hot Water Heater Drip Pan

Advertisement


Question
My home has a run of cpvc from a hookup for a dehumidifier that runs directly into the drip pan for the hot water heater.  I see no signs of damage or rust, but wanted to see if this is (practically rather than code) a good idea or if I need to extend the connection.  Water heater is about 8 years old, connection looks newer.

Answer
hi Kris,
I am not too familiar with dehumidifiers and the code will vary with jurisdictions. The only problem i see with this hookup is that one might mistake the water heater as being a leaker if observed the water in the pan. The water heater pan is not designed to collect from any other source and that is quite specific to the intent of the code although it may not be clearly defined.
Of course the dehumidifier will have some liquid to dispose of and normally and preferably that water should go to the outside of the building in that it is perfectly good water and would not harm plants or animals. Like I said above I don't know all about dehumidifiers and the statement i made is strictly my personal opinion and should be verified by some other source in that there may be some contamination from the coils and I am not aware of that. At any rate the smitty pan (water heater pan) is not designed or intended to have any other source dumping into it. It could cause one to condemn a good heater.
sorry i cannot help more.

PLEASE read this entire introduction. I have been doing this for a long time and I have come to the conclusion that if you are not willing to take the time to write a detailed question then don't expect a detailed solution! I am getting far to many questions that do not give enough detail to warrant a good solution. I realize it is a little difficult to formulate a good question but if you want a good answer you have to give me good details....read this entire introduction please....remember this website is world wide I have no clue where you live if you don't tell me.....to give more detail on the fixture you are having problems with...a one piece eljer 3.5 gallon flush will be totally different than a one-gallon flush toto.....details are important. I can answer most questions related to residential and commercial plumbing for many buildings. I have sufficient knowledge of the UPC and UMC. I will speculate for you if necessary. In those cases I will try to give you some guidance and you should use that to refine the question further and we, together, can seek the answer via a follow up. Plumbing codes and practices vary around the world--If you don't tell me where you live the answer I give may not fit your locality. I am giving my time to you as a way of fulfilling my perceived obligation to share. I am here to try to help you find a solution to your problem. REMEMBER, If you want a good answer you need to ask a detailed question and include where you live, type of pipes, type of building, water pressure if it is a water problem, type of heater, age of appliance & building all these and many more are variables that have an effect on various situations. Detailed information will help produce a better answer.
