Question

Thanks for the reply. The spring is strong and I can't take it off. I am running out of ideas. I don't want to make a bigger hole and then it is replaster the whole ceiling.

We were attempting to paint the ceiling of our utility room, and decided to remove the housing of the recessed lights. See picture with annotations for housing and mounting frame. Unfortunately, when I pulled the housing of one the lights, its mounting frame went above the ceiling as the hole in the ceiling is a bit wider than the width of the mounting frame (but not of the housing). My plan was to: (1) to get the mounting frame down and (2) put the housing back in the mounting frame which fits tightly and (3) put the whole light fitting back in the ceiling - the width of the housing is wider than that of the hole in the ceiling (and is wider than that of the mounting frame.) I am stuck at step 1. I can't get the mounting frame down, and the two springs (one shown in the picture) make it very difficult. (The springs are designed to ensure the light fitting is held in the ceiling and usually lie at 90 degrees to the mounting frame on top of the ceiling). Do you have any advice?

Thanks.

Thanks, where do you get these white things from?

2 or 3mm. thanks for your reply How do you get it out?

I am concerned that there won't be enough clearance for a standalone washing maching in a (nearly finished) refurbished utility room. Tthe builder had created a space for a standalone washing machine. On one side is a Howden's unit and on the other is a 18mm chipboard panel. The clearance on each side is a 2/3 mm and from the top of the washing machine to the new worktop it will be 10mm or less. We looked at the intructions and it says the minimum clearance for stable operation: side 25mm, top 25mm, which is larger. The builder will try to reduce the height of washing machine , or possibly make the worktop higher, but that does not address the sides. The builder has said that this has never been an issue before and he has been in the business a long time. That seems to be inconsistent with the instructions. My concerns are: - not being able to pull out the machine, - a lot of shaking of the worktop, howdens unit and the panel, which could mean they fall apart in the longer term. Washing machine vibrate a lot. We are near completion with new floor currently being laid and the worktop being installed end of this week. Are these legitimate concerns?

Thank you. When I google images of lockshields, most don't have any arrows on them whereas TRV images do arrows. I also see a pair of valves that can be bought together, one TRV and the other lockshield, and it is only the TRV body that has arrows. Have you come across lockshields that are only good in one direction?

Are you saying that I should look at the lockshields at the other side of the radiator to where the TRVs are? I had a look at them and there are no arrows on any of them.

Now down to 1 radiator that does not have any markings on it and so I don't know whether it is bi-directional. all others are bi-directional. So can I forget about it. Water circulates fine through the Hot Water Coil.

10 radiators are bi-directional, another Danfoss where the direction selector was put in the wrong direction (by the engineer I have already mentioned), and the two other radiators have no markings whatsoever. Any advice please.

I have been trying to balance my radiators and found that most radiators first get hot on the lockshield side of the radiator. An engineer moved our boiler three years ago. I now believe he connected the supply pipe from the boiler to what was the return pipe and vice versa. Trying to correct this would involve moving the pump and changing the motorised valves, and costly. I think the easiest solution would be to make sure the radiators have bi-directional TRVs. Does this really matter and would checking the TRVs are bi directional be sufficient? (The engineer won't come back to sort this. On another matter, we got a defect notice issued against him by Gas Safe, and only then did he correct the fault, and I keep discovering other faults).

Thanks very much. I couldn't find a configuration like this when I googled (yes I have an unvented cylinder). If I drain the system, would I put both valves manually into open?

I have two motorised values in my heating system. One is a three port and the other is a two port. The three port has one flow pipe for the hot water and the other for the radiators. I would have thought that was enough, i.e. be a Y plan. However, there is also a two port valve between the three port and the hot water cylinder, and I can't understand why it is there. Picture below shows flow of water and 2 and 3 port motorised valves. Can you see a reason for the two port motorised valve?

Thanks for your reply. I had a look at VDI 2035 and it seems to be a standard to reach rather than a method of removing any corrosion. Can you please tell me what you did to reach VDI 2035 without powerflusing. (Regarding your question what am I trying to achieve. I just wanted to check what the plumber was saying, as many are happy to recommend more work for themselves).
