• @transparent the tanks are sat on joists I doubled up in advance close to lower brick walls, the ply is 10mm. The blue wire is a pocket sensor that goes into the upper pocket in the cylinder.

the objection the side of buffer is the wallet that held the tank details.

the blue knob is the pressure release for mains feed

the white boxes are for the 3 port and the immerser 

the pump on the upright is for the solar water heater and it’s secure.

two pumps for the heating system one for rads and the other for dhw

i just pulled the filters out when guys here and because the original install wasn’t flushed and commissioned they are fairly contaminated, it went in on Nov last year.

An over-pressure valve on your water main?
Why?

Is mains water in your area at higher pressure than 'normal'?

The silt on that filter is the sort of stuff I get from my well.

Have you also got a magnetic filter somewhere on the rad circuit?

I don't like seeing surface-mount pattress boxes below plumbing.
The cover-plate and switch aren't waterproof.

I assume that the sparky was somewhat aware of the possibility of a leak because he's used IP67-rated cable glands for the flex entry points.

I don't know the wiring regs well enough to comment on whether there's any breach.
But common-sense tells me that the approach he's taken is shoddy.

@transparent totally agree, I've had Zoom calls with people like Ian Rippin, and been on panels trying to get better Policing around poor installations.

@transparent just had a barny with the engineers regarding my bonding. They have left the 6mm from consumer to kitchen in the loft and not connected back up where the original pipes were and pump, motorised valves etc. said they only have to bond water or gas into house and with plastic it’s safe. Aside from the fact plastic is safe there are runs of copper and water is a conductor.

 told them the wiring up through those copper pipes isn’t going to pass either. 

@david999 on the subject of silt, our system also wasn’t flushed and we had some similar brown silt, followed by a dark sludge and finally corrosive bits. This led to countless flow errors and me cleaning out the gauze filter sometimes 2-3 times a day. The good news is that we finally managed to get it clean by doing that (which was an huge pain) and for the past year our system (touch wood) has remained very clean.

@editor two days of replacing the pipes and insulation and when run up the rad valves are mixed up worse than before,  so they need to return to drain it down and start again. 25ltre hp15 down the drain. I asked them what percentage of antifreeze and they said 25ltr should be enough, no hydrometer.  Commission to them is getting the system running, they can’t check gas, flow rate temperatures or anything. I asked how they determine pump speed since my two pumps are on the 3 setting and the reply was we guess it based on the size of house. 

told me bonding is only on gas or water pipes entering the house yet everything metal in a house is bonded, then said the plastic connectors meant they didn’t need bonded apart from water being a conductor and if one copper pipe became live then so would all of them.  I also said that running the cabling next to the hot water pipes is bad practice and then gave up with them. Samsung tech out Monday it’s nearly 400 quid for this so hopefully I get a good report and will share it with you.

Once it’s drained again I will check that outside filter again but confident after another flush it will be fine. I watched on utube one company power flushing one before filling up but sadly that’s going to be rare. 

its a case of poor training, lack of skills and equipment and a mindset that they wont be checked so the quality is diluted, less work done by them but more installation done for the company. Out of sight out of mind and who really goes in their loft or under the floor to look.

the governing body are sitting on their hands taking money whilst doing nothing 

I’m quite pleased with the pipes now though, they came out with a through the wall kit. 

@david999 wow, Samsung are charging you for this?

@editor Plastic piping has been used to save the brass for their necks! 😉 Toodles.

Reason I’m getting the samsung engineer out recommended by samsung for my area.
