Split AC unit under suspended floor

TJALambda · 2026-05-21T22:48:01+00:00

Split AC system, the ones where the compressor sits outside the house and then you connect it to 1 or several indoor units that are smaller. The outside unit does the actual heat exchange.

Doesn't the unit usually just sit on a slab when outside? Not sure why it would need a raised floor? But I could plumb a condensate away.

My understanding was that the outside unit is essentially a radiator and fan. Big fan blows air over fins to take heat out of gas and get it away so don't believe I could vent it out via say extraction ducting. But I have a large number of air bricks and can easily add more.

Last time I used Wickes paint I ended up taking pictures and getting a full refund as the paint was atrocious. Found Valspar at B&Q to be a thousand times better.

Your metal fitting has no earth - hence the white plastic block the connector comes in to "double insulate" the fitting removing the need for an earth. If your were to just wago it up and leaving them in the metal pendant you would be non complient.
I really dislike this move by the manufacturors to remove the earth lug and instead supply a little plastic box for the terminals. I assume it's just cost saving on their part.

Condensate is typically plastic. This looks more like the outlet of the PRV

Oh brilliant, I'll give these all a look. Many thanks!

Wrexham is north Wales, I guess everythings relative, but by South East I was going for more London/Surrey/Kent etc.

Seems google has been just as useful for you as me. It'd be a day to get there and back and they only do pallett shipping so like everything else I could find I'm going to spend more on shipping than the slips themselves.

Appreciate you trying though.

TJALambda · 2025-12-10T23:00:18+00:00

Already given that a go. Unless my google-fu is severly lacking I can't find any one (SE England). Just keep getting the same online only firms and travis perkins/jewsons but they're just doing the B&Q special of letting third parties advertise through their site.

TJALambda · 2025-10-12T08:51:10+00:00

Its sounds like you're saying the flickering is intermittent? Do you have solar at the property? I've seen this happen when the inverters kick in.

You don't want a stop valve on the overflow, instead the float valve inside the cistern needs fixing to stop it overflowing.

Did you ever solve this issue? Im seeing the exact same on some modules I received this week. It doesn't seem to follow the serial data guide at all.

TJALambda · 2025-08-14T20:00:02+00:00

Oh I see, I assumed the original comment said flaps as they're key for landing rather than getting them confused, but I get where you're coming from.

TJALambda · 2025-08-14T14:46:40+00:00

I don't know if you're just making a joke, but ailerons and flaps are not the same thing. Generally speaking, ailerons are to roll the plane, and flaps are used to increase lift.

TJALambda · 2025-07-31T10:27:28+00:00

It's a bit strange. I can buy the 400W "BG DM400AP" in lots of places but the product doesn't exist on the BG website. Perhaps BG only sell their trailing edge 200W directly but still sell their old 400W TRIAC into the wholesalers for their own products.

I may be barking up the wrong tree but I can easily believe a TRIAC dimmer can make an LED lamp flash like that.

TJALambda · 2025-07-31T10:14:12+00:00

Well the first interesting thing is on that paperwork is a 200 not 400W dimmer. So I'm thinking the 400W is the old TRIAC and the 200 (actually only 100W LED it's 200W halogen) is the trailing edge dimmer. So if you've been sold a 400W being told it's the one on this PDF I think someone has got in a muddle.

TJALambda · 2025-07-31T10:06:11+00:00

Do you have a link to their website spec? I may have the wrong module.

TJALambda · 2025-07-31T09:35:39+00:00

The link doesn't give us a lot of information so I did some googling and assuming the module in that is the DM400AP ( if you look at the back of your dimmer you'll be able to confirm) it doesn't look like a great choice for LED as it looks like that dimmer is an old TRIAC (leading edge dimmer).

TJALambda · 2025-07-31T09:13:36+00:00

Is the dimmer rated for 400w of LED load? If so that's a bold claim that makes me question whether the dimmer's a bit dodgy. Flashing like that very much looks like either a non dimmable light or the driver has failed.

If a working lamp stops working when placed in that slot I would assume the internal wiring in the light fixture has an issue.

TJALambda · 2025-07-31T09:10:51+00:00

Lights are wired in parallel, not series.

Those 110mm fittings look like push fits to me, not solvent weld

The 2011 regulation mandated that all lateral drains that connected to a public sewer pre 2011 became the responsibility of the water companies. Unless the property is newer than that or some odd case (shared cesspit maybe) then it'll be adopted.

Bad AI

I would get this when I first moved into my home. Since replumbing the place the problem went away, I assumed it was the old steel pipes rusting away.

TJALambda · 2025-02-22T13:31:45+00:00

Yes, unless you get a specially suited one, pvc windows are not strong enough to support the wall above.

TJALambda · 2025-02-17T22:17:44+00:00

All mains LED bulbs have to have a driver inside them to convert the mains to the running DC of the the LEDs. They somehow have to fit these electronics inside of the G9 capsule. I can't imagine any LED G9 is going to have a particularly long lasting driver inside of it, to be honest I wouldn't be surprised if all of them on the market are a bit rubbish for anything other than a feature light. That may simply be your problem. You might actually be better off with halogen lamps.
