  1.  
    We are nearing the point when we board our ceilings. It has crossed my mind that we could put in place pipework for a central vacuum system in case we ever wanted to fit one. Is it possible to put in generic pipework that could be used at a later date? Does anybody have any experience of anything like this?
  2.  
    No experience personally, but having seen blockages in 2m of vacuum hose I'd rather not bother. I can't see such a system being any better than a decent cylinder vacuum like a MIELE or SEBO.

    Sounds great in theory but in the real world I'll pass

    The thing that appealed was that it would be silent so I could listen to the radio while cleaning, and also not have to lug a vacuum up and down stairs.

    Posted By: ComeOnPilgrimalso not have to lug a vacuum up and down stairs.

    My proposed solution to this was to buy two vacuum cleaners, with one maybe also being a handheld for the stairs themselves.

    But so far I've had no takers. Apparently the free exercise beats the laziness :bigsmile:

    Sorry, can't help regarding ducting. Perhaps asking one or two suppliers would answer your question.

    Central vac pipe 50mm, slow bends and tees, elbow to connect wall plate socket, vent to outside.

    Need to run belwire to each wall point too
  4.  
    I/we would not be without the built in vaccum system, a cheap Smart system installed 20+ year ago, gave ZERO trouble, despite being noisy, but taking dogs abuse(& pun intended) recently updated to a more modern quieter Beam system when I "Plumbed" in the garden room extension.
    The "Vac-Pan" kit being brilliant beside the stove for brushing the inevitable debris and ashes into.
    Properly installed it WILL NOT get blocked, courtsey of the tight 90 deg elbow at the wall socket/intake points, which picks up(and gets blocked), by any oversize debris.
    but!
    Think carefully about siting the collection unit as it will be a dirty job emptying it.

    oh
    standard size vacuum pipe, but is it 50mm or 2", being USA spec, could be either, but absolutly standard.

    I had a central systems around 15yrs ago, it was good.
    Recently I got one of those Dyson sticks and I'd say the stick is a much better option. No plumbing, no hose. Just pick it up and go.

    Yes it has a small battery and dust container. But I find I hoover little and often which keeps the house much cleaner anyway. Also emptying the dust container is revelation.

    You should definitely try it, much cheaper than installing a central system I imagine.
  5.  
    I paid just over £600.00, for the complete kit, incl a complete bundle of new pipe, misc fittings and inlets, a new 13m flexi suction hose , but no brush or stainless "shaft".
    I then paid another £60 or £70.00 for 2No. Vac Pans, incl various fittings.
    One for the kitchen, and as a late afterthought, one for beside the stove.
    These figs incl VAT btw.
    And installed it myself.(easy-peasy)
    And expect to get another 20 years, trouble free service.
    The still functional, but noisy, older unit will be retro-fitted in the shed(across the yard) for another 20 years of even rougher service, doubling up as LEV for my 2 table saws and planer.
    Knowing the £££££££££££££££££££££, the sister-in-law, et. al. have "invested" in vaccum cleaners over a 20 year period, I imagine this to be startlingly good vfm.
    Anyway in summation;
    (+)Capable of pulling the knickers off the post-menapausal wife twice a week.
    (+)Extracts monster fluff-bunnies from beneath the bed and the kitchen side board,
    BUT
    (-)The daughter had to start keeping her beloved run-of-the-house hamsters in cages.

    I have a Beam central vacuum system running in my home and I have to say it is bloody brilliant. The pipes seem to be regular 2" waste pipes but the solder type not the push fit. Mind you I'm just about to buy a cordless as well just for those quick jobs.

    Sorry I meant to say solvent weld type pipes. I guess they are airtight!

    My Sach central vac came from BPC, and was about the price of a new dyson. It took a day to fit the pipework (10 access points) and wiring (simple parallel wiring system between all points), and all the pipe was 50mm (or 2", I don't recall) solvent weld PVC. The other half says it's one of the best features about the house, and it's quiet (just an air sucking noise), plus the unit is in the garag, so my responsibility to empty it and bang the filters out once every 6 months - she doesn't do dust

    I've got quite a lot of pipe and fittings left over (not enough to do a house out with, but then again, we've come to realise we only really use 2 of the points regularly; those right in the centre of the house, the flexi hose reaches everywhere else, so there wouldn't be a lot to add to it - just some more fittings from BPC I suppose..) Pence of a job. PM me if you're interested in having it and we'll work something out

    When you're installing it, use long radius bends in the walls, and right angled ones at the access points. Pay attention to the direction that air will be flowing when installing T pieces; have air flow round the corner, not against it (T pieces have a direction to the 90 degree part of the T). When glueing pipes, put glue on the OUTSIDE of the pipe only. Do not put glue on the inner face of the pipe connector, as it can ball up into a blob when you push the pipe in, providing a catch point for dust and hair etc. Ensure that the inner face of any cuts is deburred, for the same reason (don't hack a pipe with a wood saw, and leave it all ratty/jagged when glued. Maybe use a electric mitre saw to do the cuts..

    ps in terms of blockages, it shouldnt happen. The inside of a flexi tube is ribbed, plenty of catch points. The wall pipes are smooth and lack catch points. Further, the pipes are much larger than the inlet holes that feed them, so anything that made it through the 1.5 inch hole in the handle should travel down a 2" pipe easily. The right angle at the wall point is there deliberately to catch pencils and suchlike, if you're in the habit of hoovering up pencils

    Further to my comments earlier - know it's not completly related but got my cordless now - bought a refurbished Dyson V7 animal direct from manufacturer (Dyson Outlet on ebay). It was less than half price and with a year guarantee. Fabulous and lets me reduce the consumption on the whole house vaccuum.

    So it's a win-win for me with a new recycled/reclaimed cordless offering energy savings against my big central system which is great for a full house clean but has a gutsy 1.7kW consumption.

    She's banging on about wanting one of those too, for the "i just need to hoover that up" 2 minute jobs.. Thanks for the pointer to where to get one!
