  1. But just how open a membrane would it have for drainage applications? Take the only non-woven textile I could find: Screwfix apollo weed control fabric "non-woven spun bound polypropylene. Easy to use weed suppressant roll. Reduces garden maintenance. Allows water and nutrients to penetrate the soil". Vs. Screwfix apollo driveway landscape fabric "Woven polypropylene designed for use in demanding, domestic and commercial applications. Blocks weed growth by shutting out light while allowing moisture to penetrate the fabric. Ideal for use under patio slabs, decking, block paving or professional planting." Water vs. moisture. Sounds pretty significant for drainage.
  2. Was going to suggest just screwing it down loosely and filling the gap using something waterproof (e.g. stixall) before tightening the screws a bit when thoroughly cured. PU wood glue (in my experience) isn't particularly good outdoors.
  3. Helping a neighbour out with his drainage problems here. He's dug out a 4" perforated pipe forming a french drain that runs along the front of his property - which is at the bottom of sloping ground that our houses are on. Thankfully I'm at the top. The ground just outside the front of his house frequently gets flooded and this drain has got clogged up yet again. I suggested he puts the perf. pipe back having first lined the trench with a non-woven geotextile and then fills it with 20mm stone and wraps the top over to make a continuous sock to keep silt out of the stones and pipe. This is my understanding of best practice - please correct me if necessary. The strange thing is, I can't seem to find any local suppliers of a non-woven geotextile. SF and TS have plenty of woven ones - identified as weed suppressing, as do the local builders merchants. This seems odd to me as these textiles seem more appropriate for gardeners than for building drainage, patios and drives which are more 'buildery' things. Why would this be?
  4. I forgot to put a vent position in the boot room - on the run between WC and Dining room, but I'm sure you already spotted that.
  5. Certainly. I'd concentrate with locating them in higher positions, in rooms with most solar gain in the summer. The cool air will naturally descend to lower regions. In winter these lower locations might be better heated by UFH but the FCU's can still play a part. The key to comfortable heating will be investing in systems with good quality fan control. The best A/C units adapt the flow according to occupancy detectors. I don't know if this is featured in any FCUs. I'd advise getting a demonstration of any units your were thinking of buying. A few minutes in front of one will give you a good impression of what it would be like in terms of noise and airflow.
  6. Radiators are really convectors and run 'in reverse' will just chill the air around them and create a cooler layer down on the floor. Plus a pool of water from condensing out the water vapour as @akjos says. A fan coil unit gets round both these issues by circulating the air where its more useful and harmlessly drain away any condensation.
  7. Better get your ear defenders on. They go off like firecrackers.
  8. Like after you've eaten your Donkey Kebabs?
  9. Probably got a Maxtor SATA drive past its 'best before'.
  10. Probably sooner. We had a lovely old Walnut in our back garden. Had a kids swing tied onto the perfect branch for the job. There was evidence of rot in the upper root but we ignored it for a year or so. One day I looked out and noticed the swing almost touching the ground! Overnight the tree had listed dramatically towards the neighbours garage. We spent quite a while worrying while we organised for it to be felled.
  11. Flow & return temperatures too high if supposed to be condensing.🙄
  12. Ah, the older HD boxes were a bit power hungry. Do you ever run into problems with scheduling recordings?
  13. I know. I think you instinctively know that water is conductive, so you expect bad things to happen if you mix the two. And bad things will indeed happen if there are electrical potentials around, but once there aren't, water is fairly inert. A lot of water is used in the manufacture of electronics. As @Kelvin says, LCD screens may be a little less forgiving due to their use of organic materials although it's no certain think they would be harmed.
  14. Our 1TB Sky Q box, when active, draws about 20W. Active standby is around 17W. So even if it was on all week long it would only consume 3.3kWh What model do you have?
  15. Fekkers. Name them.
  16. Fair. When's Kevin due to show up?
  17. You'd have to have a careful look at your motives for having it removed. It's bound to be more expensive than leaving it be, and it's perfectly safe if left alone. If you only want it removed so you can put in lights, then look at shallow or surface downlights
  18. If you don't get off your lazy @rse and code something up on a microcontroller, I'm going to have to come up to Bristol and do it for you.
  19. Maybe that's why it has been over-boarded. Soffit and fascia upgraders love to just pin straight over rotten wood but that gap is very suspicious. You can buy an asbestos test on amazon
  20. If you do want to wash any electronic devices, use de-mineralised water. That's what's used in manufacturing. The cable ought to have an Insulation Resistance test done on it to confirm its integrity.
  21. Bet she's got an iphone. Pity. Still reading though. Things may look up.
  22. Yes, I'm afraid Snowcrete is a premium cement - but if you want it to look right... The lime you want is a hydrated lime like this one:
  23. Electronic devices, circuit boards and components are not directly affected by water. Damage only occurs when power is present - then electrolysis begins and migration of metals will result in corrosion of the device. Knowing this you have to priorities: Remove power (disconnect or remove batteries) Dry everything (in a warm airing cupboard for example) If step one can be done almost immediately, no permanent damage will happen.

  25. And the ESP32 BLE beacon detector is discounted because?
