Installing a Mixing Valve and Expansion Tank on a Water Heater

[@Scorpiomaj27889]

Always enjoy Videos Dave! Watching this, reinforces my so much not want to do my own plumbing !! Great work , I hope folks realize just how talented and skilled you are !!!

Thank you Greg !!

You have to adjust expansion tank air pressure to match your water pressure. Everbilt expansion tank comes pre charged to 40 PSI, but factory setting on PRV (pressure reducing valve) is usually 50 PSI, so it will be under charged in many cases. Water pressure needs to be measured to know what to set expansion tank pressure to. Mismatching pressure will stress out diaphragm and lead to premature failure.

Thanks, I plan on correcting this just needed the feedback. This isn't my forte' :)

Seems goofy to be soldering copper but then also using sharkbites.

[@geraldalfano5581]

Put a one inch hook on your solder so you can reach around the the joint to apply it. Heat the joint on the opposite side you apply the solder. Clean the flux off with a damp rag and scotch bite pad after soldering or it will corrode the copper in time.

Thanks for the tip!!

[@StevenQingchengCao]

One thing i want to share is Do Not Use sharkbits unless You have to. Sharkbite fittings are always the last choice.

[@neil0502]

For any who may not know, the expansion tanks DO come pressurized, but -- ideally -- you should pressurize your expansion tank to match the normal maximum system water pressure (excluding the rise in pressure due to the heating/expansion of the water heater tank full of water) of your house.

[@ApartmentMaintenancePro]

Thank you 👍 I will do this

[@Plumbinggta]

Why you used red colour of solder, in water line connection? Need to be green

[@huntgibson3716]

Awesome video as always Dave! I see you are rocking the knipex pliers wrenches! What is your opinion on them ?

[@ApartmentMaintenancePro]

I love them - I use them for all my diy home repairs and they don’t leave the house :)

[@topher8634]

You may have a bad thermostat on your water heater Dave. I've had to replace quite a few of them due to either overheating or failure to open main valve. Rheem will send you one for free. Mixing valves are great if you need more than one temp of hot water from a single source. You could set tank at 150 and use that in kitchen and laundry and use mixing valve to lower the rest of the DHW to 120. Another item that helps with conserving hot water is a Grundfoss or equivalent circulating pump to keep hot water nearby.

Thanks for the tips !!

Never ever had any issues with Sharkbites, good job!

[@StevenQingchengCao]

not a professional plumber at all😂

[@ceciliodeloera587]

If you know how to soldier, why are you using shark bites? Stop doing things the wrong way

[@ApartmentMaintenancePro]

It’s a shark bite check valve first off and please show me one reliable source that says shark bites are the ‘wrong way’ to do things. I would use them for everything if I could but they are not cost effective

[@ceciliodeloera587]

@ApartmentMaintenancePro I just saw that you know how to soldier .Shark bites are a temporary fix, not permanent hey but what do I know? I've just been plumbing for 20 years

[@ApartmentMaintenancePro]

@@ceciliodeloera587 Sharkbites have a 25 year warranty how is that a temporary fix??????? Watch some of Roger Wakefields videos (one of the most popular plumbers on youtube last decade) on pressure testing sharkbites to the max and tell me they aren't permanent, if installed correctly. There's no code, no reliable source, that says they are a temporary fix. That's a scuttlebutt that was created many years ago backup.

[@ceciliodeloera587]

@ApartmentMaintenancePro Even Roger has said they are temporarily not saying they don't work, just not permanent
