Solar Water Heater Cooper City


Here is a video of my house showing the problem of water heater expansion, and the solution using an expansion tank.

    Always equalize(match) your safety tank pressure with your incoming water
    pressure. I noticed after your install, your incoming water pressure is 44
    lbs. Add air to your safety tank that will also make it read 44 lbs. It
    allows for a overall lighter weight to your safety tank by not allowing
    excessive water buildup inside of it, before it starts absorbing the
    pressure. May I suggest, adjusting your incoming water pressure to at least
    50 or 60 lbs. Just remember to “match” the pressure.

    Cool thanks for the tip. It ships out with 20psi, but that’s a good
    suggestion. I know my pressure is a bit on the low side.

  3. JayBird Jacobs says:

    The reason for the shipping pressure(20 lbs) is due to pressure expanding
    when being flown to different destinations by air. The maximum safety
    working pressure should be between 90 to 120 lbs. It is dictated on your
    tank label. So,feel very comfortable with adjusting your incoming water
    pressure to 50, 60 or 70 lbs with no problem. You already know your lines
    will handle 110 lbs. of pressure, LOL!

    Thanks for posting this video. I just added a PRV to our home which
    previously had none. I’ve been very confused as I’ve tried to properly
    adjust the PRV as the pressure has been so inconsistent. Now I see that
    adding a PRV with a lack of an expansion tank has caused this inconsistent
    pressure. Thanks for the video. I look forward to fixing this and to
    adjusting our water pressure properly.

    Glad it helped. Also take note of j.bird’s comments below about matching
    the air pressure to your water pressure. I did that and it works well. Best
    of luck

    Check out my video called THERMAL EXPANSION PROTECTION SYSTEM that shows an
    awesome installation. A 4.5 gallon tank on a flexible loop.

    This video was incredibly helpful to me. I have two water heaters and no
    expansion tank. That’s going to change in the morning. Thanks!

    Shouldn’t the expansion tank pressure be equal to the water pressure? In
    your case it should be 50 psi ??

    thanks….been working on the same thing afew months ago…bob

    Good job demonstrating thermal expansion in action but man those flex
    supply lines are ugly. 

  11. Jim Crawford says:

    Nice job on the video. Clear and concise. Thanks.

    Installed a new hot water tank and had to redo the copper piping to the
    tank which let me install an expansion tank. I mounted it upside down like
    you did and others did as well on youtube and one location I visited. Read
    the instructions after and found it is suppose to be installed with the
    inlet up so the air in the area the water sits will bleed out. Just
    wondering what you and others opinions are on this? Hoping its ok and I can
    keep it as is instead of taking a bunch of connections apart again.

    A plumber that came to correct some problems my grandpa and I had
    installing the hot water tank didn’t say anything about it.

    Thanks for that view of the pressure climbing on your hose fitting there.
    But wow!, that is a nice wood box! I just found the Hydroclaw mount which
    looks very good if you’re interested. I’m about to install a Marathon
    water heater in my garage and am doing research on pressure just like this.
    Thanks.

  14. Adam Tope says:

    Wherever you live do they really recommend a working pressure of 50-60 psi?
    It’s probably fine but I generally set all the PRV’s I install to 70 PSI.
    Just curious really. :D

    THESE TANKS ARE A USELESS FARCE!
    My old Rheem water heater just gave out after many years of use.
    It doesn’t heat and there is rusty colored goo seeping from the upper
    heating element cover. It is dead! It has given great service while it
    could.
    Here is the deal. There is no expansion tank here nor ever was. This old
    Rheem water heater never needed one nor have water heaters needed one for
    the decades they have been in existence. (ALL WATER HEATERS ARE FITTED
    WITH A PRESSURE RELIEF SAFETY VALVE SO THE TANK CAN’T OVER PRESSURIZE.)
    That little $50 to $90 expansion tank, (at Lowes), and associated plumber
    fees if needed is just what James (below) said it is, “complete bull
    crap”. It is just another way our government has found to make it
    economically harder on the middle class while putting big bucks in the
    pockets of the politicians who wrote the laws demanding this tank’s use.
    The gentleman above probably makes his living as a plumber so I would have
    to question his motives for pushing the use of this useless and costly
    farce.

    Do they need replaced or how long do they last?

    Fantastic! Short, and to the point. Now I know what I came here to find
    out. Thanks!

    New house..high water pressure. !00 psi..way too high..peaked at 140 psi
    after water heater pressured up, and that’s + or – 5 degrees.
    Plumber’s advice was to install a Watts water pressure regulator factory
    set at 50 psi, and one of these expansion tanks and match the pressure to
    incoming water pressure.
