  1. The mains would have to have zero pressure and empty lines for that.  Otherwise, the only place for the water to go is back into the tank (re-cycle).
     
    Edit:  As a test, you could close the valve to the tank, open the bypass, and the pump should stay off if there is any mains pressure at all.

    I did that, closed the valve directly to the tank and opened the bypass, the pump stayed off, i then opened the valve to the tank and after a couple of seconds the pump kicked in.
  2. Your pump pressure is higher than the water from the mains, so the pump is actually pushing it backwards into the mains supply.
    No need for a NRV on the bypass line if you ONLY use it when no power is supplied to the pump....however.....if you forget to close said valve when power comes back on you will empty your tank into the mains water supply.

    Thanks, yes I think you are correct in where the water was going.

    I was thinking that with a NRV on bypass I would be getting mains water pressure all the time and the pump would kick in if opening various taps or showers etc hence it would be more economical ??
    I guess that depends if the mains pressure is adequate for washing up or flushing one toilet etc ??
  3. An NRV would keep the pump from coming on but if you want to control manually (like I do), you need to shut the valve after pump out and then open the bypass valve to allow mains water direct to the house.  (which saves on energy to run the pump).  Reverse the process to use the pump again.
     
    BTW:  What you did was pumping water into the tank.

    Okay , not sure of what the main water pressure is like, it was pretty p1ss poor when we bought the house but a couple of days later had the pump and tank installed and never had cause to use it .
    I can shut valve after pump and open on bypass to give it a go.

    I think Cranki nailed it saying the pump pressure water was going back against the mains pressure.
  4. Reading the thread “ water issues “ I see that the recommendation for pump/water tank set up is :

    My set up is identical to this except instead of a NRV in the bypass line I have a manual ball valve.

     

    The valve is normally closed and, I was told, is only to be opened in case of no power or a pump issue.

     

    If I open the valve then the pump kicks in and the water goes somewhere ??, I tried it a couple of times just to see what happens but shut it off quickly.

     

    My question is:

    Would I see any benefit of replacing the valve with a NRV or should I leave it be ??

  5. My story:

     

    Working as a service engineer for a uk/us company I was asked to visit Thailand in 1991, and was excited at the thought !!, I had already traveled extensively but Thailand was top of the league !

    Arrived at the airport ( Don Muang I guess) armed with only an address of the factory and a contact name ( Kevin ).

    Kevin didn’t show so I had to get a taxi, not a problem you would think ? but after looking at my scribbled address the hordes of waiting taxi drivers all declined. Except for one guy “ okay, okay “ he said confidently and motioned me to wait as he went to get the car, I should have seen the signs [emoji849]. “600 baht “, okay I said, after all it wasn’t my money !.

    Anyway we set off in the direction of Bangkadi and it was apparent he didn’t know the way but after asking directions after more than an hour or so we arrived.

    The factory was quiet but luckily the security guard was on site as was the plant manager Charles. Charles ushered me inside and asked me how much was the taxi , “600” I replied, he looked aghast “600 !, no way give him 200 “.

    I had agreed with the driver for 600 so felt kinda embarrassed offering him 200, the taxi driver got down on his knees begging for the 600.

    I was in the process of getting more money out when Charles exclaimed “ wait, that’s not even a taxi !! “ and shouted something to the security guard.

    The guard reached inside the gatehouse and produced an ancient rifle, which was obviously very old and looked quite comical, pointed it at the taxi driver who got back in his “ taxi “ and drove away.

    I was feeling quite guilty, after all the guy had got me here when others had declined, and regretted not intervening and giving him 3 or 4 hundred. Charles explains that recently some Japanese visitors took the same route and were robbed, beaten and left for dead in their shorts out in the rice fields so tensions were running high against dodgy taxis.

     

    My 10 days in Thailand consisted of me leaving the hotel in Bangkok early to beat the traffic, working all day in a hot sweaty environment ( Kevin looking down from his air conned office [emoji35]).

    Leaving the plant to a local bar for food and drinks till the traffic died down, driving to my hotel for a quick shower and then Kevin’s driver taking me on to meet up with Kevin , and others, usually in Soi Cowboy, staying till around 2 when the bargain basement girls were offered ( I declined ) then back to collapse in a heap on my hotel bed for what seemed like 5 minutes !!

     

    A pretty common visit experience for anyone, only exception being:

     

    Around 6 weeks later ( mid may) I was at a driving range with my buddy and I was feeling a bit off so after a couple in the pub I retired early.

    Woke up in the middle of the night burning up, into the bathroom to cool down, cold flannel on my head and laid in the empty bath. Ex wife accused me of being drunk !! and left me there.!!

    Went back to bed and slept, next morning woke up, bright yellow, even the whites of my eyes were yellow ! .

    Yup, hepatitis A , my souvenir from LOS !!

     

    Would be 24 years before I went back, to a new factory, the one in Bangkadi ended up under 6 metres of water for 2 months during the flooding !!

  6. The ability to change tempo and mood successfully, the hallmark of many a great musician.
     
     

    Thanks for this, I’m painting the house right now so earphones plugged in the iPod and away I go [emoji51]
    Long time since I played any Dire Straits but this album brings back great memories !!

    A far cry from the stardom of the late 70’s and most of the 80’s ( with a short reprise in the early 90’s ) which followed Dire Straits around.
    Here’s Mark teaming up with James Taylor on an unusual song about the Mason - Dixon line but it works very well and indeed the whole album has some great songs with Mark’s excellent, if slightly restrained, playing.

    Mark Knopfler - Sailing to Philadelphia

  7. Another vote for Lazada, you can use the filter for local ( in Thailand ) and Cash on delivery.

    Cash on delivery is a great advantage IMHO , applies to many stuff o/seas as well.

     

    Lot of cheap junk on there as usual but great if you are looking for something specific, want it delivered to your address in good time and can pay COD.

     

    The last 3 items I bought from Lazada arrived in 6 days or less from China and I paid the delivery man cash in hand, he will also allow you to check the item within reason.

    I’ve never had to return anything but I understand it can be done easily from any 7-11.

     

    Give Lazada a good check out before you discount them.
