Handiman is replacing gas water heater. The current heater is old and has been leaking water on the basement floor for a while.
So I have a few questions. Do we really need one of those air expansion tanks ? there will be the overflow pipe that runs towards the floor.
And Can i use plex in anyway, would I need a manifold, or does this really not make it easiler to install?
It's in the basement of a house and we are replacing tall with tall. Same gallons. Gas waterheater. --184.215.xxx.xx |

I always replace the shutoff valve and add one to the hot, these get brazed in. Then use the braided flex water lines, but never a flex gas line, be sure that shut-off works well also, when you get any inspector called out and you have good working shutoff valves they look kindly towards whatever the original problem was they came to inspect. --75.94.xxx.xxx |

Patty, I believe St. Louis County requires one per code, but not at my properties in Franklin County (not sure about Jefferson). I copied some information about why you may want one from a website - if you have a back flow preventor on your house, it looks like you need one. With that said, I have a back flow preventor on my personal home and we do not have an expansion tank (gas water heater - 11 years old).
A water heater expansion tank is designed to help prevent fluctuations in water pressure. Fluctuations in water pressure can damage a water heater and water lines in the home’s plumbing system. The water heater expansion tank serves as an overflow receptacle by absorbing excess water volume that the water heater creates when heating water. Since water expands when it is heated due to thermal expansion the water heater creates extra water volume every time it heats water. The extra water volume creates excess pressure in the plumbing system. This extra pressure can cause damage to the water heater, fixtures, and water piping over time.
Many homes have a closed system which is a water system with a one way valve such as a backflow valve, check valve, or pressure reducing valve. In a closed system this extra water pressure from thermal expansion can cause the most damage because the extra water pressure has nowhere to go since it cannot push back into the city water. Most cities require that expansion tanks be installed in closed systems. If you have some form of backflow preventer installed on the main water line you may be required to also have a water heater expansion tank installed. Check the local building code or call the building and safety department to find out.
If you do not have a one way valve installed on the main water line, and therefore do not have a closed water system, you may still benefit from a water heater expansion tank. Expansion tanks are normally installed above the water heater on the cold side before the water comes into the water heater. The extra hot water from the thermal expansion can be stored in the expansion tank and when hot water is demanded it is put back into the water heater. Having an expansion tank helps prevent dripping faucet and running toilets by keeping the extra built up pressure from reaching the fixtures and prematurely damaging them.
Water heater expansion tank prices start at around $40 and the tank is easy to install with a normal 3/4” threaded connection. A tee will have to be installed above the water heater if one is not there already. If you are hiring a plumber to have a water heater installed it’s a good idea to get a price for the installation of an expansion tank also. It may not be much more than you are already paying if it is done at the same time. If you are installing a water heater yourself consider installing an expansion tank even if it is not required since the benefits far outweigh the work and cost involved.

If you're in st. Louis county and the inspector at your next occupancy inspection sees a new heater, he will probably check to make sure a permit was pulled before he passes the house. Happened two out of two times for me. And yes, the expansion tank was required by code. --172.56.xx.xx |

this would be like working on my own house. But the budget is tight now, so are installing ourselves with some experience. St. Louis county, no occupancy permit or other such, unincorporated. More like a homeowner working on relatives house. Thanks for all the above, I"m reading some now on google. May just have to repeat what is there as it works now! --184.215.xxx.xx |

Near the inlet valve located after the meter add a new house line valve and a tee with an elbow pointed upwards and a length of pipe with a cap to act as the expansion chamber - this works with the new meters which have check valves built in. --75.94.xxx.xxx |

If I was asking those questions, I wouldn't be doing my own install.
Call a licensed plumber. --24.128.xxx.x |

Pretty sure your code will require an expansion tank. I'd be surprised if not.
I had a handyman do the water heater at my personal house. Next time I'm using a plumber for piece of mind. The handyman got it right but I'd rather pay the extra 100 bucks and have the guarantee of his license behind it. I've become risk averse as I enter middle age :-/ --205.201.xxx.x |

Here any gas appliance must be installed by a certified gas fitter with a license. If anything happens then insurance is going to be a issue. Gas fitters carry special insurance if anything happens. Here gas codes are constantly changing where what was permitted in the past is no longer permitted. The last commercial coin clothes gas dryer had to have a tag which was installed by a certified gas fitter. Check with local building codes to see what is required. --74.220.xxx.xx |

Geez people. It is a water heater.
If your neighboring counties use the expansion tank, I would opt to install one.
Lowes sells a nice Made In USA soft black hose kit. The ends use a compression fitting to catch your 3/4" copper.
When you are finished use some soapy water on all the gas fittings. Gas leaks make big bubbles. It is really hard to have a leak. I've only come across loose fittings a few times.
Take an extra moment and check that the vent pipe is strong and not rusting from the inside out. Try to crush it with your hand. --173.66.x.xx |

Expansion tank is probably required by code. However, I think the addition of the expansion tank is relatively new (maybe in the last 10 years?) and I don't personally know of any adverse effects to my prior personal residences or current rental properties of not having one.
I think these are about $50 at the big box store and could probably be installed by your handyman. Add a tee in the cold water inlet with a threaded adapter. Install the expansion tank and adjust the pressure as per the instructions. --74.232.xx.xxx |
