    As I mentioned my maximum during a power cut is 0.3~0.4 Bar, more importantly all the pipes are 32mm up to the outlets and virtually all bends are 45 degrees so friction and turbulence losses are small.
     

    This means that we have walking water during power cuts and have no need for any stand by tanks and as it is plumbed we don’t need to take any action. Sure the heaters turn off but that doesn’t stop the water flow mid shower, obviously  since the supply pressure drops from 4 bar to 0.3 bar the flow drops, but as designed it doesn’t stop. So all in all it functions well enough and as expected when it was designed in the house planning. Would an 8 metre tank be better? Of course, but it would have needed a separate structure. As is the tank location is built into the house.

     

    living in the boonies we get frequent power cuts, so designed for them. My usual cooking is on an induction hob, beside it is a gas hob so little difference and no inconvenience. 

    I think where we differ is in what we consider reasonable flow and pressure.  I think we can both agree that 4 Bar is reasonable pressure.  I run my system at that pressure as do you.  Is 0.3/0.4 Bar or even 0.8 Bar reasonable during a power cut?  You say yes.  My view is no, as in not worth bothering putting a system in place to achieve that result, but my view is influenced by the fact that power cuts here are generally of short duration.

    Mr STWW is of course correct in that if you can maintain 0.8 Bar at the shower head then you can have a reasonable shower… provided of course you use a suitable shower head. 

    Well you could have 0.8 Bar at the shower head in a power cut if the tank was maybe 9 metres above the shower head; which his tank almost certainly isn't.

    You may be the OP hasn’t said that he is, in fact if you read carefully it would only be gravity feed when there is a power cut.

     

    You clearly have a poor understanding of the possibilities of plumbing if you think that having a high level tank means that you can’t/shouldn’t  also have a pump and that that the supply pipe size and routing is only relevant with a pumped system. 
     

    The larger diameter pipes and smooth routing are far more important when there is no power. Pumped or not makes a difference to the losses but they are usually only noticed when there is no pump.

     

    If your system was supposed to be pure gravity feed then your supply pipes should have been better designed and sized.



     

     

    Yes.  I know all that.

     

    I was talking about the performance of the system under gravity feed.  If you look at my earlier posts I made specific reference to the performance of the downstream system in my second post before you chipped in.

     

    The OP is interested in what happens in a power cut.

     

    I know all about pipe diameters, the angle of the bend and yada yada yada.

     

    Try addressing the OP's question.  Performance when there is no electrical power.

    Pressure or flow, it isn’t really that important, the point is that your supply pipes from the tank are too small or badly routed so you have significantly high losses from friction and turbulence.

     

    A water tank at 8 metres with good plumbing will give amply strong showers. If yours didn’t QED your plumbing was causing the problem.

    The OP and I are talking about a system without a pump.  Gravity feed only.

     

    The only way what you say makes sense is if you are talking about a pumped system.

    If the pressure is that bad then it’s your supply pipes that are badly undersized or have poor routing.

    Wrong.  Pressure is determined by the height of the tank less pressure losses in the system downstream.

     

    It is basic physics.

  6. At 5 metres your water pressure from the water tower would be 0.5 Bar less pressure losses in the pipework thereafter.

     

    I have a water tower you can have for free.  It's 8 metres tall and made from concrete ????  I discontinued using it because the water pressure is feeble, power cuts here are generally less than half an hour and I don't want the liability of people working at 8 metres height on maintenance and repair.

     

    In your situation I think I would either go for a generator or buy candles and torches.  Bear in mind that a generator would have particular maintainance requirements by virtue of infrequent use.  Also bear in mind that if you use a generator you must not backfeed power into the electricity grid.  Imagine some poor soul up a ladder trying to fix the problem and you are pumping power into the system.

     

    I went for the candles and torches option.

    On my Formula 1 car I prefer to have all four tyres matching.

     

    On my Hilux I'm happy if the tyres are round and black.

    I watched a vlog recently where Nico Rosberg interviewed Alain Prost.  He said that one of the ways he gained a competitive advantage was by mixing compounds on his F1 cars.  On certain clockwise circuits, for example, he might choose to have three medium compounds and a hard rear left.

     

    I think Alain was fairly unusual in this approach but there you go.

    WordPerfect wasn't a bad little word processing program actually.  I learned my first spread sheeting using Suercalc on a 14" green screen with no mouse, a 386 with 640k and 20M of memory. That was when you had to actually know math to write the equations - I was counting open/close brackets in my sleep.

     

    I asked the predecessor of the IT specialist (known as The Computer Guy) if he could upgrade it to 1M of RAM - he asked me what the hell I was gonna do with a Super Computer.  When I told him it was because Larry the Lounge Lizard was playing a bit slow, he saw my reasoning.

    I worked in programming in the late 1970s in Burroughs Algol.  The programs were entered using punch cards and debugging of programs was done in multiple 24 hour cycles.  A hard disk drive (multiple disks) was about the size of a washing machine.  1MB of RAM was cutting edge stuff.

  9. The headline figures are not real.

     

    Because the system does not work you have:

     

    Multiple applications by the same person

    Multiple acknowledgements and approvals to the same person.

     

    It works the same way with call centres.  If they are understaffed they will say they have 100,000 callers a day.  But actually they have 10,000 callers a day calling, on average, ten times to get a response.

     

    My guess is nobody knows the actual number of people approved under this process.

    They weren't exactly banned in 2002 in fact the 500 cc two-stroke or 990 cc four-stroke bikes were specified to race in MotoGP.

     

     

    Your memory of the detail is better than mine.  What I should have said was that two strokes were rendered uncompetitive by a rules change.

     

    I think a two stroke 500 won one race in the season where they competed against the 990cc four strokes.  But on most circuits that season the four strokes just romped away in a straight line.

    If you want power why mess with silly little 2 strokes engines with wam bam stupid little surge of speed power when you can have a full on continuous power from a 4 stroke.

    Don't you think motogp would be racing 2 stokes if they were better than 4 stoke.

     

    2 strokes don't race in MotoGP because they are banned.  Manufacturers switched to 4 strokes because they were compelled to.

     

    That said I accept that a 4 stroke is a better choice than a high performance 2 stroke for road use.

    Well I was there when we bought it, and I think it was 3 year payment plan.  it was 90000 or 100000 baht cash price before interests.

    It wasn't a crash it was something in the engine.

     

    It's just a month's payment she'll miss, I just can't see the reason why they wouldn't let her pay extra the next two months, since it'll be more expensive for them to reprocess it.

     

    It's a relatively expensive bike, since the smaller normal scooters with the 125 cc engines was for sale at about 20000 baht

     

     

    Last time I looked Honda warranty was three years or 100K whichever comes sooner.  Given the bike is on 3 year finance why aren't Honda picking up the repair bill?

     

    125cc Hondas start at about 55K new.

    Simple solution....you will not do extension based on marriage. Also will not use money in bank retirement. That leaves you with extension retirement based on monthly income. If that's also a no no then I guess pack the bags for Europe.

     

    Yes.  Income is not an issue.  My wife and I have enough of that but then you are into a whole new world of Thai BS paperwork.

     

    I explained way back in this thread what I am going to do and the reasoning so no point in you offering your 'solutions'.

    Not obvious to me. Funds held in banks in my country Oz obtain 0.25% currently. Not a lot loss of opportunity cost in that.

    Anyway enjoy your application for extension based on marriage. 

     

    I specifically said I would not do an application for extension based on marriage above.

     

    And security of the banks, transferability and exchange rates are significant issues to me.  More so than interest rates.

  15. Interest on bikes in Thailand is insanely expensive but even so 3450 a month is nuts for a PCX150.  That's a one on every street corner cheap bike.  Ask her for more detail on the exact terms of the deal.

     

    And 6000 for a repair bill.  What the hell accounted for that.  A major engine blow up might explain it but highly unlikely on what must be a fairly new bike given that it is financed.  A fairly big crash could explain it.  Maybe a shop that ripped her off?

     

    I think you need to ask your GF some very specific questions.  And certainly don't throw money at this situation.  You would get more satisfaction burning it.
