    Dispute over where to locate water pump.

    Not wishing to repeat all the questions like what in JxP's thread, I want to know how important is locating the electric water pump 200w.

    I have 2 concrete water bowls that I have connected 1/2 pipe to and run approx 5 meteres to the pump. It doesn't work very well, so the shop I bought the pump from said my pump was too far from the source ( concrete bowls ), however the guy that did the work disagrees and is fukkin about with the pressure thingie on top of the pump, dunno what its called.

    I also have a well that is some 30 - 40 meters from a Luckstar 250w pump and that works perfectly. It is pretty much a straight line to the well and probably aslightly larger pipe, whereas the configuration to the bowls has at least 5 right angles in it.

    Any ideas anyone ?

    I wish I could do these jobs myself, but I never did woodwork or metalwork in school, and I sucked at the sciences.

    Sounds like the pump is pressure fed from the concrete bowls,i.e. the pump does not have to suck.
    The 5 metre run won't cause any big problems.

    Has the condenser been checked ?

    More clarity please.

    Would you be so kind as to sketch a diagram? What is the H/P & pump out displacement, (LPM or GPM)? I never heard of watt output assuming the amperage is .86[at]230vac. Also, FTHD [at] given displacement output?

    Can you tell us the pump model number ?
    We are just assuming that you have a suitable pump.
    Is the pump being fed water or does it have to suck?
    How far vertically does the pump have to lift the water.?



    The condenser is on the pump and has two wires going into it.
    There is no adjuster on it.
    The dodgy electric supply in Thailand blows them occasionally.

    Magix MJ-200 Size 1" x 200 watts

    The 2 concrete bowls are on ground level abd I wish to have it to use when the community water ism't on. i.e. when you most need it.
    It will send water to 2 tapes in one house and to the gas shower, bum gun and sink in the other.

    Our requirements are minimal which is why I bought this pump last week.

    If it is automatic why is this guy fiddling with that little tower on top of the pump ?

    In the tower is a adjustable pressure valva, just a little screw thing, turn it up and the pump works on a higher pressure, turn it up too much and the pump will cut in and out for no reason and burn out.

    Can't find it on google.

    I would never supply a 1" pump with a half inch pipe.
    Better to have two half inch pipes feeding a 1" and then into the pump.

    200w should easily supply two faucets at a 4 metre lift.
    If your pipes are not restricted then it must be the pump.
    Unless you are pumping water back into your main supply.
    Does the pump cut in and out when you open a tap ?

    In my experience: Don't ever screw around with that pressure valve. It's protected by a screw and the guy who sold me our pump said Mitsubishi will only provide warranty if the valve has not been tampered with. That turned out to be an ominous prediction, we did try to adjust the valve (which never really worked well at all) and in the end broke the pump. A write-off. No warranty.

    If you don't get enough oomph out of your pump get a stronger one. Depending on the stuff that it has to feed, it might need more than you think. Or it might simply be broken - who knows.

    The solution for us was a new pump with 280 watts (instead of 250) and now we get decent pressure everywhere. Not touching the valve.

    If your water lines are too long or too windy, you'll get a lot of friction loss.

    I think what is being discussed is a pressure switch that starts the pump during low pressure and shuts it off when high pressure is reached.
    and if your pump will shut down before the water pressure is high enough then it can be changed by unscrewing it and take it to the shop and there is on/off pressures stamped on it and you can buy the one that is set for the pressure you need.
    They seem to not last to long as in 9 years I have had to replace 3 of them on our pump.

    This sounds good to me, you might need a valve on the inline from from the mains water, so it only goes into your house and not back into, the under pressured mains system. Does it pump water when not connected to your house line?

    Right thanks everyone so far.

    I have changed things as above. The jars are connected at the bottom with 1/2 inch pipe, but the water in and out pipes are at the top of the jars. The feed to the pump is 1 inch and the feed to refill from the mains is 1/2 inch . The 1 inch pipe to pump is just over a metre.

    Does it work ?

    No. All the faucets work but the shower is just a dribble.

    Have checked for blockage and dirt, so where do I go from here?

    Forgot to say the pump is sitting on flip flops on a pile of bricks at the same height as the top of jar, roughly head height 5'9"

    Have you got a check valve on the main supply line?

    yes we have a valve on the mains water, I'm trying to make the jar water work, nothing to do with the mains.

    Yep Norts, that goes through the wall to the shower room all - ground level

    Turn it off and the check valve feeding the jars, then try again.

    As long as you are not pumping back into the city supply, I don't see any problems with your set-up. You could try running a 2" feed to the pump and see if it helps.

    This why I suggested closing the check valve from the main and the one feeding the jars. Need to isolate the pump.

    If he has a check valve, there is no need to close it because they only flow in one direction. If he has a normal gate valve, then yes, close it.

    Good point. If they are check valves, they may be the problem. Normally the valve for the main is a gate valve.

    I would estimate at least 50 percent of check valves (one way valves) bought in Thailand do not work from new.

    From my experience you are being optimistic.

    Maybe that is why my pump cycles every 10 minutes or so.

    Using 1/2" pipe is a bit miserly, but I don't think the problems are just caused by that

    I do know that the 3 I have bought here have never worked, almost everything I have bought here has a very short lifespan.
