Urgent advice needed about hot water

[Riley]

It may have sorted it for you but it's not right you shouldn't have to turn down the water going through the Combi it should restrict it to a suitable lpm allowing the boiler to heat it properly. Post a picture of what you've altered

It doesn't let me put the image up, it keeps saying denied and forbidden. I have found a pic of what it looks like when not attached to a pipe vokera cold water inlet stopcock.

This doesn't make any sense! Not dismissing your suffering at all, but as someone said earlier on, if the hot water were stored there could be a possibility of some contamination. As it is, your hot water is nothing more than your old water running through a heat exchanger. If the cold water doesn't bring you out in a rash, I really can't see how the hot can. Even if we accept that warming the water encourages some sort of microbial growth, the water is flowing, and heated on demand, so there's no time for bacterial or fungal growth!

I just cannot see how turning the cold water isolation valve down to reduce the flow could prevent the skin irritation, unless your skin is very delicate or thin, and the hot water flow is really strong, and causing a sort of abrasion injury to you? But then I'd expect the cold to do the same...

Very very odd! I hope you do get to the bottom of this!

Email your pictures to [email protected].

One of the mod team will post them up for you.

Have you been tested for allergy to lime scale?

I took off the wooden panel which was covering the pipes and was inspecting the pipes and valves with the boilers' instruction manual and which way is the filling loop meant be facing such as the valves? There are two black levers at each side and I was reading something about a non return valve could this be something to look at all as they are both facing clockwise.

Actually you could be on to something there.. If the NRV is sticking open then system water could be mixing with the cold water going into your boiler, contaminating that, but leaving your cold water supply uncontaminated...

We need photos of that pipework. There will be an arrow on one or both of those valves on the filling loop. Close-ups showing the valves and arrows would be particularly helpful.

Okay so I have taken some photos of the filling loop and valves (sorry they aren't exactly the best). On the black lever on the right side of the filling loop there is an arrow pointing upwards yet the black valve is facing another direction. With the black valve on the left side of the filling loop I can't see an arrow pointing anywhere on the valve. Any further clarification on this thank you.

You've been adjusting the filling loop? If so mate this is rubbish

No, from descriptions in previous posts I think he's reducing the cold inlet flow into the boiler with the square black knob on the inlet pipe.

The position of the black valve handle on the right is fine - it shows that the valve is closed. The handle on the right shows the valve is open, and it should not be. Actually, to comply with water regs it must not be, and the braided hose must be removed from between the two valves unless filling the system.

The right-hand valve is facing the wrong way but that is not the non return valve, the left hand one is, and there will be an arrow on there somewhere. Please have another look and post the photo..

No I haven't touched the filling loop but adjusted the cold water inlet stopcock. How does the filling loop seem, as I am not sure if the left side of it is turned the right way because the black lever is turned fully anti-clockwise and I am not sure if should be turned clockwise or not (see previous pic) I will take another picture.

You need to turn the left hand valve of the filling loop to the off position - ie crosswise to the valve body. It should turn 90 degrees clockwise.

I have now turned the left hand valve of the filling loop to the off position (fully clockwise) I took a picture of what it looks like now does it seem okay because before it was turned fully anti-clockwise.
P.S I had asked my landlord for the boiler installers' details and he said that he couldn't remember and gave me a number instead, but the number he gave me doesn't exist anymore.
