Plumbing qeestions
Hi guys,
I'm replacing a hot water heater tomorrow at my rental property. A few questions. I have to at some point join galvinized with new copper.I noticed that everywhere else in the house that this was done they used a union that I'm not familiar with. Can't you screw a male copper fitting into a female galvinized joint? Is it possible/to code to hook up a short flexible gas line to connect the black pipe to the water heater? This would seem alot easier then to find black pipe the exact lenghts I need to hook the existing pipe to the new gas inlet on the water heater. Thanks,Drake

After doing searching on some plumbing forums,it appears that I do need a dielectric union to join galvinized to copper (or brass).
Looks like I can run up to 4' of flex gas line to the water heater also. I've never seen flex line run to a hot water heater in my life,but seems like it would make things a little easier for me.

Thanks.
I have not seen one of those before. I'll have to see if they have something like that at the home center where I shop.

Should of asked before, why are you changing tank, Is it to old, leaking or just short of hot water? I ask because I almost changed mine 2 years ago because of short hot water only enough for one shower and it was the dip tube ($10) It is plastic and breaks down . Very easy to change!!

Mine is leaking where it corroded around the water inlet on top.

You can easily install a dielectric union, which is what you need. When copper & galvanized are directly connected, pipes can corrode to the point of failure. I'm not convinced that the nipple will work as well. I have heard that a brass nipple can isolate the copper from the galvanized well enough to prevent pipe failure.

Yeah,it should be no big deal to put one of those unions in. It's just that when I went over to the house to look at the plumbing I had never seen one before because I never really had to deal with galvanized.
It sure helps to DIY or I could never keep a rental profitable.  I only call in someone if I'm swamped at my job,or an emergency. Now if I could find an all night store for 3rd shifters like me.  No sleep again tomorrow I guess. Thanks guys!

I recently had a copper water line start leaking at my rental house, which is 125 miles away. The leak was pretty bad when it was discovered by the tenant on a Sunday, so I had to get it stopped.
I went to the local Home Depot to get something to cap the line, and he recommended using something called Shark Bites. This is a special compression style fitting that can join copper pipes or PEX type pipes. I cut the bad section out and replaced it with a section of PEX tubing. It was quick, required no torch or heating, and did not leak. I also cut out a valve that began leaking and replaced it. They make a host of stuff that will mix with copper. Here's the link. http://www.pexsupply.com/CategoryPre...D=588&brandid= |

I had seen those talked about on a plumbing forum. I could not tell if they would be compatible with galvinized pipe though.
 Seems like they are compatible with PEX and copper line. I didn't see them at the first store I was at (which was out of dielectric 1/2" fittings),but I did see them at Home Depot. Problem is,at my local HD you can never find ANYBODY to talk to,so I just bought my dielectic fittings.

you need new flex lines for the water supply and hot water outlet which both do not need a dielectric fitting and a flex gas line. no big deal.

Generally you are not permitted to directly connect the plastic lines to the water heater. Most codes around here require a minimum 15" of copper before you connect a plastic material such as PEX or CPVC.

missed it, thought he was talking about metal to metal, no plastic or PEX involved.
