Default Issues with Hot Water Mixing Valve

After a few years, these valves, attached to your plumbing near your water heater, start to cause temperature of water problems.

This video provides good advice on how to check and repair one.

These are part of the house plumbing and not part of any water heater rental contract or warranty. If installed properly, removing it is very diy friendly.

Easy to buy and install a replacement too.

That explains some weird water problems we have once in a while.. I was mostly blaming 60 year old plumbing.

Default Mixing valve

Thanks for creating the thread. Does anyone know if it's a code violation to remove it? Will I have to replace it when I go to sell my home?
Thanks

Removal would create a code violation yes. I would plan on replacement prior to a sale. Any decent home inspector would flag it. Its also the proper thing to do.

As per the video, a repair is easy and free. Replacement is also easy and <$100. So why wouldn't you do one of these I'm thinking.

Yes agree have looked up my part and it appears to be about $110 - just wanted to seek out my options. Will aim to repair or replace. Thanks again.

Mixing valves seem to have about a 5-7 year life span in my experience working on water heaters

My shower mixing valve(the actual hot/cold valve) crapped out in about 4 years, i replace the cartridge for free(moen)

The Mixing valve above the tank started acting up on mine at about 7 years. I removed cleaned and flushed it out and it worked for another 2 years. LAst summer removed it completely. It was much cheaper to install two of these

Of our three showers our first one died this year, after 8 years. Went to Home Depot (Barrhaven) to pick up a replacement and was surprised when they told me it was free. They keep the replacements in a box under one of the shelves so you have to ask for one.

Either way I will have to get someone in to do it - I have to get a wrench that will fit the thing to get it off and I don't want to start the repair myself (the online DIY videos always look easier than it is) and then be stuck without hot water until I can get a plumber in if it doesn't go well.

Are the mixing valves covered under a rental agreement? Curious...
