  1. He's on hols mate
  2. Ok, next up is available plant space and some plans maybe? The flow will naturally reduce with demand, but if the restrictors are selected properly you won't be stealing all of the available flow. You need to give ADEQUATE flow to each shower to guarantee results, OR you fit a second accumulator. A Zimlet 500L will set you back a bit less than £600 iirc but you can check on the PumpsUkLtd website under accessories. That'll give you dimensions too if you look under downloads on the same page. FYI, running 5 showers and still having a bit of oomph for other outlets is nigh-on commercial territory, so dont expect to do this on a shoe-string budget, it'll need some moola throwing at it. FWIW I would ditch the notion of the single electric shower and go all mixers. Instead, used the immersions ( 4 x 3kw in a 500 is possible if ordering bespoke ) as your failsafe, so you'll still have DHW even if the boiler goes down. Pointless in just having one working failsafe electric shower unless its in a communal bathroom ( if the 5 showers are all ensuite then no-one is going to want to share the only working shower with 4 others ). The sparky will have to be on board with this design too, so involve them as early on in the process as possible.
  3. This is the one ive got. Change the heads over for 1/2' or 3/4" tap connectors, but the head also move so it will do varying sizes too, like the back nuts. As you apply pressure it tightens its grip.
  4. Just turn the taps off gently for now, and fit a small water hammer arrestor vessel ( EV ) when you go to mains.
  5. It's not banging in the new stuff, it just sounds like it is. It'll be water hammer due to the new taps being 1/4 turn instead of 10 turn.
  6. Forget the rapid set. Trust me, you'll spend more time panicking and cleaning out dead or dying mixes than tiling.
  7. Do you still have access from underneath ?
  8. Ground floor in screed or 1st floor on joists?
  9. Yup. Just the tanking solution to bed the membrane in.
  10. Seems like a nice, straightforward job ?
  11. Make sure you clean the underside as sometimes they're contaminated with mould release agent and then nothing will stick to it. Make up a little dry sand / cement mix to use like an Ajax and scrub it in with a sponge. Do this directly before laying the tray. Use a flexible tile adhesive to bond the tray down. Any recognised make will be fine, but I purposely avoid Unibond as I've had a couple of bad experiences with that make refusing to go off. Whatever your bonding to, make sure you prime it with a flexible primer not PVA. Ultra is what I normally use. First coat 75% water and leave to dry ( 1 hour usually ) then 50/50 directly before putting the tray down so your more or less bonding to wet primer. If your feeling brave use rapid set, if not use standard set so you've got at least 30mins to adjust it. Lay with a 10 / 12mm notch trowel and stay about 50mm from where the seal of the trap hits the tray. The adhesive will squeeze over a bit leaving only an inch or so un-bonded which is fine as typically you'll not ever stand on / directly next to the waste anyhoo. If there is any serious undulation in the floor eg 0mm-6mm-0mm again then notch the underside of the tray as well. If no serious undulation then just notch the floor and 'butter' the underside of the tray, the idea being to bring two lots of wet adhesive together for a guaranteed full bond.
  12. ?? "Haaaaaaaleeeeelllluuuuujyaaaaaaaaa" ?
  13. Lol. Buy some wellies. You need to isolate the 3 pipes or your going to get very wet. Remember to isolate the electrical supply so you don't get electrocuted as well as drowned
  14. Need to know as it'll be heating the system. If it's only a 24/28kw then we may end up going W-plan aka "DHW priority" where it doesn't do space heating and hot water together and any time the hot water needs topping up the system will divert from heating to do so by design. The hot out of the combi will just do the kitchen sink so it ( the moving hot water components etc ) stays active, with the heating output serving the rads and UVC via the W-plan arrangement. Controls can be discussed on a separate thread if you like, when a system is firmly decided upon.
  15. No need. You run them all together and then see if they actually need restriction first. If you have the accumulator ( remembering that until we have the details of the main this is all hypothetical ) then you'll have a guaranteed X litres per minute flow, so restricting them will then leave some pressure / flow for other outlets, such as kitchen / utility / cloakroom WC etc etc. Look at it like having a nice V8 engine but only going at 30-40MPH, but you have the option to briefly open the throttle a bit more when needed.
  16. Just fit one of these onto the end of each shower hose, then the handset
  17. The manifolds can be made to have as many outlets as you require. You would simply connect the electric shower ( yuk ) to an outlet of the cold manifold. Same for the basins / sinks / baths / showers. Simplicity itself, and you can make outlets live as the build progresses. If an item fails, you can just isolate that one outlet and leave the rest of the house working.
  18. The UVC is fed from the cold supply. The cold supply is connected to the accumulator, recharging and discharging accordingly. I'll post a diagram in a bit, easier that way
  19. Now that's progress !! What a difference .
  20. Yup. Spin it around and it should be sorted.
  21. B is typically DHW. As this should be a W-plan then DHW should be set to priority. The above is a mid-position for reference only, and the valve you ( should ) have should be the diverter version.
  22. Yup. Electric showers are the anti-Christ.
