I have some heaters with little clearance overhead. It would be hard to remove the anode rod. My questions are:

1) How long is a typical anode rod?
2) How would you get the old one out if there is little clearance (2' or less) over the water heater?
3) What type of metal in an anode is preferable?
4) Are those linked flexible anode rods good? (I fear they will fall apart at the links)
4) Is there a standard sized socket for removing anode rods?

Thanks

I have some heaters with little clearance overhead. It would be hard to remove the anode rod. My questions are:

1) How long is a typical anode rod?
depends on water heater. about 2-3 foot avg. I've seem them longer.

2) How would you get the old one out if there is little clearance (2' or less)
over the water heater?
you could cut it and use flexible or telescopic one to replace it.

3) What type of metal in an anode is preferable? most are magnesium or aluminum. Preferred is magnesium, imo. Really depends on type of water you have.

4) Are those linked flexible anode rods good? (I fear they will fall apart at the links) I don't have any personal experience with them. If space is limited you may not have a choice unless you want to drain, and disconnect/tilt water heater to change it out. You can google customer satisfaction and read up on it.

4) Is there a standard sized socket for removing anode rods?

Thanks
1 1-16, 1/2 inch drive with long breaker bar using extra leverage. Best to use impact wrench if possible. Easy peasey. The above are just my personal opinons as a diy homeowner.

There is no "typical" length or socket size.
Depends on the size of the heater.
What makes you think it need to be changed?

not really, but how many times have you flushed all the junk out of the bottoms? if not on a regular basis like 6 month intervals, the stuff bakes on into a solid mass..then the bottom plate of the heater super heats and warps causing leaks...if gas or oil fired..electric not so much..

If you decide to go forward with the anode replacement let me suggest a 6 point socket rather than a 12 point. Also an impact wrench isn't all that common in the usual house hold tool bag and if you don't have one a 2x4 about 3 ft. long makes a hellofah impactor if there is room to swing it. In certain situations I usually tether the wrench to keep it from possibly impacting body parts and or other valuables.

I usually charge for these kinds of ideas but this first one is free.:biggrin2:

The powered anode rod is much better than a sacrificial anode rod in zinc or magnesium material. A powered anode rod can serve 10 to 20 years while zinc anode or magnesium rod can last for 2-5 years life span. Powered anode rod no need to replace, since it has much longer service life.
