Is this manifold insulation safe?

Hi…

The pipes under the tiles are not insulated when fitted. This under stairs area is becoming sauna when the heating is on.

I insulated the pipes as much as I could to prevent heating this space. I don’t know how to insulate the horizontal bars under the actuators and the flow red stuff.

This will not solve the problem of the tiles here becoming hot so I am thinking of laying a plywood board and leave some gap near the walls to prevent stressing the tiles and pushing them to crack.

But for the pipes… is this safe for the manifold to run like this? Any other tips are most welcome.

Is there a reason plumbers are booked out for weeks when electricians seem slightly easier to get hold of?

Not a complaint just genuinely wanna know. Every plumber I've contacted recently has a wait that surprises me. Wondering if it's a training pipeline thing, a regional thing or whether demand has just gone up in a way the trade hasn't kept up with yet.

New concealed shower nightmare

We’ve had a string of problems with our extension build over the last year - including our builder going bust and leaving us in the sh*t.

Anyway the latest (and hopefully) last thing we’re dealing with is the plumbing in our en-suite.

Last week we discovered - after it was tiled - that the cold water feed for the cistern, was actually a hot water feed. Hmmm cosy
Anyway we managed to sort that as there was access to where the pipes tee’d off

Now we’ve come to the shower - which is a concealed thermostatic style. Guess what - yes it looks like the cold and hot inlets have been plumbed wrong way round.

When you run the shower it’s either scalding hot or freezing cold - nothing in between

Stupidly - I did test before tiling, but assumed when it ran warm all was good 🙄

So - before I strip the tiles off and hack away at the wall to re-route the pipes - any thoughts on if this might be fixable via a less disruptive method?

The hot and cold inlet pipes run in the ceiling (concrete base) and then down the walls.

Kitchen tap removal help!

Hi,

My tap broke. I have a replacement but can't seem to remove the base plate from under the sink to pull the old unit out.

I have removed what I thought was the primary fastener from underneath but this thing is seriously wedged and barely moves.

Any advice please!

Replacement temperature control no longer made, what are my options?

Hello,
So the temperature control in my shower upstairs is no longer made so need to figure out how to replace. The unit is tiled into the wall. I’m reluctant to knock out tiles to replace the shower unit. What are my options? Thanks in advance

Bathroom Radiator sizing (can't find what I need)

I have a bathroom radiator/towel rail (hot water type) that needs replacing. It measure approx 520mm high and 610mm wide, the pipe centres are approx 565mm. I have looked online and can't find anything that I can swap this one out for.

I have found plenty 600mm wide but the pipe centres for these tend to be 550mm and that's not going to fit the existing pipework (the pipes come out through tile just to make it worse). Additionally as this bathrrom is under a staircase I can't go any higher than about 550mm.

Does anyone have any advice for what I can do? I can't believe this is some mad custom radiator as the previous owner of the house tended to cheap out on things like this, but I can't find anything.

Thanks.

Boiler placement in loft conversion

Hi, just looking for an honest second opinion please.

During our loft conversion, our plumber advised that the new combi boiler could not be installed above the new staircase area / near eaves due to flue regulations and servicing access, so it has instead been placed in the loft dressing room area on the opposite wall of the house, pretty much directly opposite.

However, I’ve noticed a neighbour appears to have a very similar setup with the boiler likely in the eaves/ above stairs and a vertical flue near a Velux window.

Based on these photos, do you think an eaves installation would likely have been possible/compliant in my loft, or does the current boiler location seem like the correct approach?

Not looking to cause issues, just trying to understand whether there were realistic alternatives before we finish the room around it, as I’ll rather do this now and have the space back in what is going to be a small walk in wardrobe than wish for years that I would have done this.

Thanks so much

Washing machine won't drain, unsure if it's the machine itself or how it's plumbed in

Our washing machine won't drain. It's been fully drained manually, and I've pulled it out to check the grey drain hose wasn't clogged.

Has everything been plumbed in right under the sink? Worried that the sink waste pipe is angled down towards the machine's drain pipe and it's doubling back on itself.

I'm aware the valve is off in the photo!

It's a rented property and we've had issues with it since we moved in, in December.

Just want to make sure we're not going to have the same issue if we buy a new washing machine!

Thanks in advance :)

Can someone tell me what parts I need to get to replace these with please?

We’ve had a leak in our other toilet so I want to replace all the parts in this toilet so it doesn’t happen again. I know for the other one I bought some basis fluid master parts but they don’t look the same as these so I’m wondering if there’s a specific type I need to get?

Thank you!

Can anyone tell me what this adjustable valve is for?

My Warmflow external oil boiler leaks water from this adjustable grey valve at the top of the circulating pump housing. I'm guessing it's some sort of relief valve. The overflow pipe to the soffit coming from the Feed and Expansion tank is also dripping a lot more than previously and the heating system seems noisier than usual when the pump is running, especially when on hot water only. Would this be caused by sludge in the system? I had several radiators replaced last year and the system was drained and refilled three or four times. Inhibitor was used every time and there is a magnetic filter on the boiler. I do have to bleed the radiators a lot though so I'm guessing there's a leak somewhere also. If anyone has recommendations let me know. I can manage the replacement of the pump and the draining and refilling of the system, but I'm trying to understand what's actually happening with it before replacing anything. The pump is working so I'm hoping I don't need to actually replace the pump itself.

How to de attach this valve from the pipe?

I’m trying to replace the fill valve and this plastic bit is monumentally stuck. The brass pipe seems to come in at a slight angle which doesn’t help. Any ideas? Thank you

Thoughts on this interaction?

I called a plumber to come and have a look at a shower leak - they came, had a look at it, removed the shower head and left, stating they would be in touch.
I just got a phone call today telling me that they would have to replace the whole shower because they could not find the appropriate connector between the pipe and shower head. I don’t have the means to replace the whole shower at the moment so said I would think about it.
The man on the phone proceeded to tell me that the visit was £70 which I thought was ridiculous - nothing was fixed and I now have an open pipe and a shower head in my bathtub and no solution. When this was pointed out to him, he got mad and basically told me that I should never call their company again for work. I had never been charged for basically no work being done and was very surprised but maybe I’m in the wrong? I’m an architect and would never charge a client for a first chat consultation although this would mean I would take some of my time to meet with them.

If anyone is interested - basically the pipe is 18mm and the shower head is 22 which I understand is standard - the previous owner had done a bit of a botched job putting the two together. I felt that ordering an 18mm shower head would be the simplest thing but this was rebutted by the plumber.

Toilet issue

Is this a partial clog or drain issue? Only downstairs toilet does this - downstairs sink occasionally gurgles when I plunge toilet also. No blockage in kitchen sink or upstairs bathroom as far as I can tell. Have contacted waste supplier to check our drains. UK terraced house.

Is this in use?

Recently moved into a 1950s house, the chimney breast was bricked over with another separate brick wall. After taking all the bricks off I found that the fireplace used to have a back boiler so there’s old redundant pipes that I want to cut..they’re not capped so I don’t think there’s any water left in them or anything..there’s also this pipework. The radiator pipes come down the inside of the chimney and exit into the kitchen feeding into the radiator so I know the ones on the left are fine and won’t be touching them.my question is can I remove the one with the drain on it or is it connected to the radiator system..I haven’t tried opening it yet to see if it’s dry or being used but it just seems like a really strange place to add in a drain at the end of the system..any thoughts would be greatly appreciated

Advice needed for a non plumber!

Hi! Help needed. The extent of my plumbing knowledge is that I know you can turn on a tap and water comes out… We just had a survey for an ASHP boiler and our water pressure is very low (he said flow rate was 7 LPM to current boiler). He suggested changing the connection to the incoming mains might help solve the issue. Do you amazing people agree or know how to fix it? We have no water leaks and the pipe from the mains was replaced around 8 years ago by water company.

oil tank replacement - advice needed

Hello all

We live in a village with no gas supply. We have an oil tank in our garden.

We are having our garden landscaped and we want to place the tank to the side of our garden so that it’s out of sight. Given the space we have, we thought it best to replace it with a slimline bunded tank.

We have received the following quote and I would like some thoughts on whether this seems reasonable as it seems pretty steep to me!

Drain, remove and dispose of the old tank - £400
New bunded slimline 1250 litre tank - £1659
Service valve - £20
OFV Kit - £45
12m pipe - £75
Fittings - £46
Labour - £600

Currys washing instillation

Hi there,
Had a washing machine delivered and installed from Currys today. Guy said something about having a plastic valve that can fail, which I think may be a cover up, he had hid the hoses behind the machine and when I looked had tapped up two different parts. The blue connection is leaking, not bad just dripping. Sorry I’m not very technical haha. I’ll be contacting them but any ideas why he’s done this? The old machine wasn’t leaking and didn’t have anything taped. Thank you

Tips on saving water when showering with a combi boiler?

Looking for advice on how to save water when showering with a combi boiler. I’ve tried turning the water down when I’m shaving and cleansing my face (just enough water flow to clean off my razor as I go and wash the cleanser off) but the water quickly goes ice cold and then takes forever to heat back up again and, even then, it changes temperature constantly for the rest of my shower. I’ve also tried turning the shower completely off when shampooing my hair etc but, again, when I turn it back on the temperature goes completely out of whack. Because of this, I have to have the shower on full blast the entire time I’m in there, as any slight change to the pressure turns the water cold. I have very long and thick curly hair so washing it with low pressure isn’t really an option. Boiler has been checked and all is working fine.

Is there any way to combat this issue, or is this just something I have to live with due to the nature of the boiler? I’ve seen these shower heads online that have a button to stop and start the water flow, but I’m not sure if this would actually work in this case.

Any advice really appreciated!

Is my CH incorrect?

Hi,

I have a problem radiator which is always way cooler than it should be. It has been flushed and balancing attempted. And just recently it had been replaced, but the new one suffers from the same issue.

When it was replaced I also had a small one removed which involved taking up a floor board and I took a look at the pipes and took this picture.

https://preview.redd.it/hspyvozi9y1h1.jpg?width=3072&format=pjpg&auto=webp&s=f49c859a54a47dcfca4886527b357c165acfb451

You can see a pipe coming out of the problem radiator, which I assume is the return because it is cool and the other radiator pipe is hot. You can see the two pipes which went to the other radiator. All the pipes are hot apart from the one coming out of the radiator.

What I find odd is that there is a short pipe between the flow and the return pipes. Wouldn't this be a short cut that would reduce the flow through the radiator?

This diagram makes it clearer:
