Most small expansion tanks have no drain--only an air valve for the bladder--so it makes no difference with that type--- The old style big ones with a drain need to have the drain down,obviously. Agreed that it does not matter.

Water Heaters – Expansion Tanks. Tank was mounted Input down meaning it looked upside down but the new installation is opening up. (thermal expansion tank). Does the orientation matter on a bladder type expansion tank: water side tapping up, down or sideways? The only time I use an EAS(B&G enhanced air separator)is if I leave a steel tank in the ceiling at which point I'll install a tank fitting as well and pipe off the 3/4' tapping that the EAS affords me up to the tank.

Two things to consider. Installing it in the upright position will require less fittings. If you install it in the upside down position, you'll have less water dumping out when you remove it, but it will take more fittings and you'll likely have to do more work to support the thing. I prefer installing them upright directly on top of the cold inlet.

When the bladder in the tank fails - and it will fail at some point - then someone will have to disconnect the tank. Water weighs 8.3 lbs per gallon. As mentioned earlier, a 2 gal tank - not too bad, a 5 gal tank full is 41 lbs plus the weight of the tank. If the tank is easy to get an arm around then no problem - if it is an awkward position then the fun begins.

So, the installer should ask themselves, while installing for the first time, 'How is this puppy coming off when the bladder fails and it is full of water.' Each heater install is different - if there is room above the WH then that's where I put the tank - draining is easy, gravity is your friend as long as you press the valve to vent the tank. If there is no room above the tank then go lower but accessible. The worst install is one that you can't get to easily.

Re: Expansion Tank Install Author: caja715 (Non-US) okay, not sure what my reply was that seemed silly, but lets give it another stab re the air: if you hang a tank upside down and there is air in the lines.oh and water does have air in it.the air goes into the expansion tank the air rises to the top and rests against the bladder. The bladder if I recall from the cuttaway I saw a diapragm with the shreader valve on the other side. The shreader on an expansion tank isnt going to do anything for the air pocket on the other side of the diaphragm.

You hang the tank down,it has water sit in it (like it should) expand and contract,,, yadda yadda yadda, and the air.

Re: Expansion Tank Install Author: mjb1962853 (NY) Any air that gets trapped inside a 'tee-up' expansion tank (on the WATER side of the bladder) will eventually go back into solution and disappear. This will not have any significant impact on how the tank works or how long it lasts. A bladder expansion tank will work fine in any position. Whatever is easiest for installation and maintenance for the specific job is what you should use.

I've had them in both tee-up and tee-down positions without any problems. Some type of support is usually a good idea and I have one even on my little 2.5 gallon tank. Re: Expansion Tank Install Author: TxFLSTC (TX) Most if the info on the web indicates that you can install an expansion tank vertically up or down, or horizontally sideways, or even on a 45 degree angle, anywhere on the cold. While technically correct, it seems to me that tank up, connection at the bottom, close to & above the HWH intake would be best; Water would drain out of the tank, eliminating or reducing stagnate water.

Semi stagnate water would go into HWH, hopefully sanitized, >140, not into cold drinking water. Completely drain each time system de-pressurized = no stagnate water Would still function if bladder broke. Katekyo Hitman Reborn Subtitle Indonesia Mp4 on this page. Bladder could still be checked by de-pressurizing system, if tank psi holds bladder ok.

Would drain out when replacing = low weight. Please note: • Inappropriate messages or blatant advertising will be deleted. We cannot be held responsible for bad or inadequate advice. • Plbg.com has no control over external content that may be linked to from messages posted here.
