Finding parts & supplies in Los Angeles?

I’m in south Los Angeles county and am wondering if anyone on here is from this area and could recommend a local place to get parts / fittings / hoses / chemicals / etc without having to order everything online?

Or do you guys know of any national ag supply stores that carry this type of stuff I might be able to check out?

I’d like to get some of the EBC stuff that has been recommended to me to try out on my next job as well as have a local place I could go to get advice, buy fittings, get 12.5% bleach, etc.

I’ve been to the local hardware stores and they don’t really have what I’m looking for, and I’m not having any luck google searching for a place like “pressure washing supply store” in my area.

Try equipment rental or paint supply
