Hi experts,

I intend to replace my (electric 50gal) water heater. Can you tell me about three codes I will have to there to for the inspection? I can't find the detail I need for confidence t'll pass via google searches.

1/The platform is 'recommended' to be secured to the floor or wall (according to a 2004 PDF I found). Mandatory requirement?
2/Does the power supply wire need to be in a metal conduit? Mandatory?
3/Do the two seismic straps need to be secured with minimum mandatory length lag bolts and are there mandatory maximum angles for the plumber's tape (corner mount) that are going to cause a fail?


Thanks, I want this to go smoothly!

There are a couple of pros that frequent this forum from your location. Please wait for one of them to respond.

They will help you out with the seismic codes so your instalation goes smoothly. Thanks.

I don't plumb in CA. but when I come across questionable or unclear code requirements I call my local 'authority having jurisdiction' (AHJ) They will clear up the grey areas for you.

Is this the 2004 PDF you are referring to ?

If you talk with the AHJ, I would double check that it is still the current guide. I believe it is, but it doesn't hurt to ask.

In Code language recommended means exactly that. It is not required. Even strongly recommended is not. But, if they recommend it, I tend to follow it. If you follow the recommended items, it sends the message that you are not trying to get by with the bare minimums.

If the wires are in a cable assembly, they usually do not need to be in conduit. If they are individual wires, they do.

The lag screw sizes and the bracing angle question is answered within the PDF link I provided. If you have trouble with the plans, post your question with reference to the page number of the method you are using.

There is the possibility that there are code changes that affect your installation either electrically or plumbing that may not have been picked up on a prior replacement. You might want to take your PDF and a couple pics of your current plumbing and electrical with you when you go in to pickup the permit application.
