I carried out a test report which identified a lot of code violations, too many to list in the time frame allocated for the test. So an estimate was submitted and we are busy doing the repairs. I cannot understand how companies can do test reports and issue COC's unless the building is unoccupied and every single part of the installations is accessible.

While carrying out COC audits, I have noticed "no access" is a common excuse.

The geyser wiring and bonding was one of the violations on this site, which looks like it was replaced recently.

You can see before the geyser was replaced there was an earth wire from the meter box to the mains water copper pipe, that has been cut, and the wire is just hanging loose. A piece of the copper pipe has been cut and replaced with polycop. Now you have to ask yourself, the mains water is galvanised steel, which connected to a copper pipe , which is connected to polycop which is then at some point connected to the old copper pipe again, then connected to the geyser and out the other side of the geyser still using copper, do you bond the piece of copper pipe?

To add to the mix, an additional geyser has been installed and piped using Pex, which is connected to a piece of copper pipe on the side of the building.

I noticed the bonding strap is still hanging on the pipe in 2 locations but not secured.

The geyser has a piece of surfix hanging from the geyser isolator to the geyser (3 m long), no gland on the terminal cover, which is a common site after the insurance approved plumber has replaced the geyser.

I have a huge earthing issue on this site, old steel conduit is used for earth continuity. So the simple solution is going to extend the original earth wire hanging loose to the closest electrical point in the building which will be the old stove isolator point and secure it to the metal box or remove the locknut and fit an earth tag and hope the pipe between the stove and the DB is not cut and removed.

At the DB I will fit an earth bar and run a 4 mm earth wire to the geyser, from the geyser to the outbuilding and any other points I feel could improve the general earthing of the building. I might even knock in a earth rod or 2 at the pool DB and maybe at the outbuilding DB. All the old fuse boxes will be replaced with circuit breakers and earth leakage in each DB.

2 expensive mistakes I have learnt this year,

1/ Never offer to fix an alarm system wiring, just replace all the wiring and dont be a putts and leave the old wiring in place.

2/ When you are called out to do an inspection report on a house with fuse boxes, the amount of faults you are going to find will cost more to repair than rewire.
