here's a better view

Holy crap, you mean there's an inlet on the underneath? I wonder why its not leaking. I never plugged it off.

A1 would you care to highlight the problems . I have looked at the installation, apart from insulating the pipes and maybe an extra seismic strap , it looks ok , all the required valves are in place from what I can see ,

Cheers Peasea

^^^ditto^^^

restraint ok - only 2 req @195L, all safety valving is there including what one would have to assume is open exhaust/vent on hot side of wetback coil

maybe additional support to hwc stand, maybe a drain point for coil would be good, maybe lose some of the m+f elbows, lack of insulation is about all I would pick on

Haha A1 your taking the piss i bet you did this install and you put it here trying to see if anyone could pick holes in your work..hahaha...Ok here we go.

The vent pipe is on the piss
I wouldnt use PTFE tape on the TPRV only because i dont trust ptfe tape
I wouldnt put a crox on an annealed pice of pipe(i have seen the crox let go before on a boiler line because of this, granted it had 3 storys of head on it)...instead i would have pulled those wetback lines to give a nice long radius bend to help with flow.
The bottom strap on the cylinder is not to code 100mm max from base of cylinder
There is no 50/50 vertical blocking full height of cylinder as required by the code 3500.4 figure 5.4
I cant see the 30/2mm thick washer on the coach screws as well
3500.4  7.1.3 (a) (4)  those flow and return pipes should be lagged so no kiddies or anyone else gets burnt
3500.4 figure 7.1 long radius bends(3D min)so you need a 75mm radius bends minimum and that bottom coil connection is deffinatley not a 75mm radius bend.
Tempering valve? 

But apart from those few minor things it looks neat and tidy...lol

Im Just taking the piss A1.

haha     


better than my effort!!

temp valve if you zoom in is solar rated/yellow-orange top!! so ok there-although would avoid the bute/dux swivle elbows on it!!

forgot it was open book these days!!

Hey guys thanks for the critique! You're right it is my work, and its always good to have other plumbers check out what youre doing from time to time especially when you work for yourself by yourself like I do!
You're right about the cylinder stand. I thought it was a bit lightweight as well. The builders apprentice built this and I was under a time constraint so I just had to carry on. I told the bilder I wasnt happy with it and he assured me he would put some thicker timber underneath the day after.
Threadseal on tpr valve? I thought you had to use ptfe rather than hemp? I remember getting pulled up for using hemp at hutt valley polytech many years ago?
Youre right about the lagging. I hate bringing myself to lag copper though....it looks so pretty!
A drain point on the bottom coil would have been a good idea also, and Ill definatley do this on my next install. Good spotting~
Ive never understood or agreed with the building code on the 100mm max from top and bottom of cylinder with your strapping.
Im a stickler for following the building code to the letter most of the time, especially with hwc installs, but lets face it guys, if we all restrained ourselves to the building code 100%, I dont think any of us would be in business or get any work done.

Cheers, guys

strands of hemp getting into the valve. Some valve manufacturers even asy not to use hemp in their instructions. Its a load of bullshit if you ask me. Thread tape can get into a val;ve just as easy as hemp can, and if you do it right, it shouldnt happen anyway!

Interesting! I didn't know hemp had a temperature limit! I've never heard of this cloth stuff
