I have had systems with old non pressure balanced valves have cold or hot water cross into the lines and then the hot water never got totally hot. For clarification, that is what i meant by cross connection.

Hey Andy, thanx for extra info. You know I have installed the grundfos version of this product and they have always worked. Even if there were 2 branches as long as they were both quite a ways from the water heater, even the bath without the valve would benefit alot from installing just one...

Andy, I am wondering how many of the valve kits you installed. If you look on Watt's website they tell you that if you have quite a few different branches on your plumbing system, you may need to get a valve kit for each bathroom. I think that is your problem. I am very careful about the way...

I will show that to my wife... she is sure I haven't made a good call in years!! Pat

Thunderpaw, I do not know where you are located but Noland is a chain of plumbing supply stores on the east coast. They have been bought out by someone, as they were family owned for a long time but, they still have stores on the east coast. There is one in Raleigh NC where I am from. I am...

Whoever the chemist was that created poly should be spanked!

Hey Timmer, I don't know. My inspectors are pretty firm on visible permanent access, but if you are not getting inspections that is up to you. Pat

Timmer, mr.david is correct. I believe they are a backwater valve and cleanout and you do need to leave access. The backwater valve is there to prevent raw sewage coming back into your house from the city sewer if they have a backup out there at the street. The sewer cleanout is used to rod...

med student, the grey "poly pipe" is a slightly different outside diameter than pex (which is red, white or blue), but you can join the two of them together. At a plumbing supply store or lowes you can get what is called a poly - to- pex transition coupling. It is a coupling that has a poly...

phish, you know, in this industry every idiot has the answers and never listens to anybody. I always promised myself that I would ask every more experienced plumber I met for his tips and tricks and it has served me well to not be a young punk know it all. Thank you for your advice... very...

phish, i will check my code book in morning. Will be curios to see if our are the same. I have not looked at that passage for some time, but my guess is you are correct. I am curious why you think it would be bad plumbing practice. I have never plumbed that way myself but in case i am ever...

I would invest in tankless water heaters. You could use approximately 3-4 Rinnai Tankless heaters piped together as shown in their installation manuals, using a common digital controller to set the temperature for all the units. That would save you money in the long run as they only heat the...

YNY, Ao smith and State are same company. Standard grad for State is the Select Series. The premier series that has 10 year warranty gives thicker insulation, better "blue diamond" glass lining, better dip tube that cleans tank, magnesium anode rod instead of aluminum, and sand hog elements...

Hey CT, I agree with speedbump, do not go over 75psi as that is what prv valves for city water max at. I like to set mine around 45-65 and unless you have a shower with multiple bodysprays and heads that should be fine. Also consider adding a larger bladder tank. Most "builder" houses...

I agree with Mr. David. I am impressed with the fit and finish of the Bradford White heaters. I have been using State (which is owned by AO Smith along with American) and am really considering switching. I have never had a problem with Ruud/Rheem but the supply house that sells them near me...

Dan, I believe it is. I am in North Carolina but we use the International Plumbing Code (with NC Amendments) and if neither fixture uses a pumping action such as a sump pump or washing machine it is acceptable. I am not sure if New York has amendments that would negate this but I believe you...

Hey amkaos, I am curious about your project. Is there a lavatory in the bathroom and how old is the plumbing or even the house in general. I liked Mr. David's drawings and to be honest i do not know much about ks plumbing codes. For curiosity sake I also wonder if wet venting is allowed in...

I agree with Mr. David. Without having to do a lot of calculations, 1" water piping over 40' with no appreciable rise will not result in a significant loss of pressure. That being said as speedbump mentioned the unit with 1 cubic foot of resin will result in 8-12 psi of drop. If you change the...
