JunctionCity Maint

Yahoo Message Number: 88421
We are in Winnimucca, NV headed for Oregon. Thinking about going to Junction City to have our Hydro-hot mixer valve replaced. Of the great facilities there who has experience with any of them to suggest someone who is good on Hydro-hot. I was warned that replacing the mixer valve could crater the entire unit. With that kind of risk I can live with the varying water temps. Suggestions welcome.

Floyd,

How much did the 330 cost installed? I'm thinking of getting one. I'll be there next week.

Thanks,

Michel

2nd vote for Carrier & Son. They replaced our mixer valve 2 years ago, did a great job. I've found if I turn the adjustment knob through it's full range once a month or so it breaks loose the crud build up that causes the failure.

Lyle: I've replaced the mixing valve with the new design. Got the parts from Roger Berke and he provides very excellent instructions. Not too big a job; probably about one hour if you're familiar with the unit. 1.5 hrs if you're new to it,

It took about 1hr to install and the cost was $1295, and it was the best 1295 that I have spent. Tells you everything you need to know and some from day 1. Next year will be going down and having the side cameras installed.

First thing is come up to Washington and have a look around & come by and I'll fix you up here at Infinity Coach.. Smile
Second thing is (or really the first) has the mixing valve been rebuilt. If so then I agree replace it. If not then get the rebuild kit (watts #70A RK) or http://www.homedepot.com/p/Watts-1-2-in-Hot-Water-Tempering-Valve-Repair-Kit-70A-RK/202564444#.Ua_KSILn8dU
Easy to replace, hardest part is if access is tight.
OR if you decide to change it, it's only on the fresh potable lines, so not much to mess up while changing it. I can't think of anything off the top of my head that could "crater"? the unit. Might get REALLY hot or cold at the faucet...

My mixing valve has always been in the max position. So, we use very little hot water mixed with cold water for showers. As a result, we can take back to back showers on electric.
I guess we are not actually asking the mixing valve to do any mixing, so maybe that means it won't fail. I never exercise it.

Comments and opinions welcome.

George,

I am trying but either I am missing something or I don't understand the logic. The mixer valve is between the hot water output of the HydroHot and the cold water supply. Basically it is there to prevent scalding from the very hot water leaving the unit (185 degrees). Typically the mixer is set to maintain the hot water at the faucets at 120 degrees. That is well below the scalding point for a human but still above the comfort level of most people. (114 degrees). So using the 114 degrees as probably your comfort level then it takes the same amount of cold water mixed into the hot to get to that level whether you mix it all at the shower controls or the mixer valve does most of it first.
Now we also left our mixer at the max setting but for a completely different reason. My wife wants really hot water when washing the white load of clothes. Also now at home she wants the hottest water possible for the dish washer. Yes our dishwasher will reheat the rinse water but it makes little sense to me to cool down the hot water only to reheat it with a costly electric element. With that in mind we are willing to risk accidental scalding while washing the dishes or taking showers. I might take a different view of it if we had young children around a lot.

Hi, Don

I'm no expert on the HH, but I do my own servicing and have performed several repairs. It is my impression that the mixing valve serves as a tempering valve that combines cold water with the hot water out of the HH boiler so as to regulate the temperature of the hot water side of the domestic water system. So, my thinking is that the hotter this setting and water is, the less of it that will be needed for a comfortable hot shower.
My question, that no one has commented on, is whether keeping the mixing valve on full hot will help avoid failures. Or, on the other hand, should the mixing valve always be exercised to prevent problems? Like you, I am not concerned with scalding.

I don't how what the temperature rating is of the plastic water pipe in our coaches but it might be something to think about. I would bet it would be expensive to replace if damaged.

Just a thought.
