    Water Pump Suggestions/Advice.

    I'm moving next weekend to a rented property, but the water pressure upstairs is poor so I need to buy a water pump. I'll only be renting the place for a year, and within that time will be building a house on the wife's land (he said...), then I'll take the pump with me, so I'd prefer to get one which is well made and will last. The pump won't be stressed much as it's a small 2 storey house, and the house we're building will be on 1 floor with raised areas (a couple of metres).

    I've never bought or considered a water pump before, so I was gonna pop down to Homepro and see what they have; I've been told that you can get an okay pump for 5000 baht. What's your advice?
    How do I post these pictures???

    This is 7,000 baht or so at Homepro.

    4,000baht mitsubishi will do you, you will most likely need a water tank also, probably find the mains water only works a few hours perday.

    ^ Any reason why, Paps?

    ^^ okay, I've seen these yellow Mitsubishi water pumps at other houses in the village - I'll check them out.

    Is it better to have the tank higher (on the 1st floor and have the pump fill it up then gravity do its thing when you need a shower) or just on the ground floor and let the pump take it up when needed?

    The missus says the water is on 24/7, I will check...

    I have bought a few of these over the years with no issue what so ever.

    You can even buy them at Tesco Lotus.

    Stick with the Japanese models and stay away from anything from China

    One thing you need to think of is the distance from the water main to the house.

    This will determine how much pressure you actually receive with a smaller pump

    The smart idea is think ahead to what you will need in your new house and buy that size now.

    The difference between a smaller pump at 4,000 to 5,000 and a large one at 7,000 to 8,000 is not so much that you don't want to be buying twice if you do not have to

    The pump will need to be on its own power source with a circuit breaker

    If your rental is on city/town water supply, no need for a tank as it is constant flow 24/7

    ^ makes sense, I'll go to Big C, Lotus and Homepro today, see what they have. I check with the FiL about the water pressure on the land, so that buy the appropriate size when we move the pump there.

    Something like this, DD?



    or a bigger one like this:



    I saw this one at 1 of the neighbours place.

    4,000baht mitsubishi will do a 3 story house, I use a 6,000baht one for my 6 story place with the tank on the roof, ie 7th story it is pumping up to, it is on 24/7, been working longer than 10 years, only changed the small tank on the pump for a stainless steel one as dogs kept pissing on it and the old one rusted, nice pumps mitsubishis and never a problem with the motors in the first 5 years at least, I've fitted hundreds.

    ^ that is just the kinda setup I'm thinking about, although I probably don't need a tank for this Bkk place.

    I don't see a manbag, I see a shopping bag.

    (Right, I'm off to BigC and Homepro to have a look, I'll report back with the prices and colour options. )

    There is one problem with that set up, if your Missus forgets to pay a poxy 600 baht electric bill, and they come and take your Meter away, you too will be resigned to crouching underneath the wall using the outdoor shower

    BB,

    Opposite Klong Toey market on Rama IV if you are near there. There is a row of hardware/tool shops 2 or 3 have water pumps plus spares should you ever need them.

    Betty,

    Pumps are rated by PSI or pounds per square inch/atmospheres in EU. You can rely on the pressure rating to overcome gravity if you select the right pump. the set up pictured assures one that there is always "positive pressure/head," on the suction side of the pump therefore assuring you that there will be water to the outlet source.

    That said, as DD has said he has installed numerous pumps and does his selection by price which equates to GPM rates and PSI. He has been successful in doing so it appears. Not very scientific, but it works in his case.

    I have two tank supplies for my single family dwelling 2 stories, with one buried tank and one above ground SS tank. the water main feeds from the city into my above ground tank w/float to shut off supply. The above ground tank gravity feeds the buried tank/plastic black type common here also fitted with float to shut off when full and not in the feed aspect to the pump. the pump has an filtered suction about 6 inches from the bottom of the buried tank and pulls suction feed to the house outlets when in demand. I have good pressure but not great. I would prefer a few more PSI/GPM but I also don't know the allowable pressure on these plastic pipes and their glued fittings. All seem to be rated at 40 psi, but one never can depend on PVC.

    As previously stated be sure to put on its own separate breaker and be sure to ground the pump. If you are smart you'll also install water heaters in your bath and in your kitchen water supply during this process. Don't go cheap.

    Yep, we have the same. Even though it was submerged in flood water for a month it is still going strong. Seven years old it is.

    I seem to remember reading somewhere on TD that it is not legal to instal a pump directly onto the water pipe as it leaves your metre ? You have to have a storage tank that fills up on mains pressure then you pump the water from the tank into the house. This is to prevent people sucking the water out of the mains which could affect the mains pressure in neighbouring houses ?

    Is that right ?

    Thanks everyone for your replies.

    At Homepro they have the Mitsubishi yellow ones as pictured below. The prices are:

    4,300 baht 100 watt.
    5,000 baht 150 watt.
    6,000 baht 200 watt.
    7,000 baht 250 watt.

    (if the missus' translation is correct...); they are all the same size/type, just a different power rating. What do you lot reckon, is the 4,300 baht 100 watt gonna be powerful enough for the 2 storey building (no water tank) in Bangkok, then change to a house in the country with a tank - DD reckons the 4,300 is enough, and he has the experience so I believe him. Is there any benefit to getting the 150 watt one at 5,000 baht, as it's only a bit more, if it offers more power and/or less stress on a system then I'm hapy to go with that?

    ^
    Depends how many taps/faucets you expect to have on at one time.
    A 100w pump will drop flow at the shower if a tap is turned on elsewhere in the house

    ^ okay, thanks - do you reckon we need a tank? I'd rather not bother for this rented place. The missus has said the pump without out a tank should have a designation WT for this type of house. I have no idea what she is talking about, she has been talking to Thai 'experts'...

    ^^ I'm thinking worse case scenario is the washing machine on whilst the MiL is having a shower and I want to have a shower too (not the same one...) - does sound like a tank would help...

    Yeah, we needed a pump and tank for a business and put both on the second floor...

    Thot it would have been logical right by the meter...but would have been busted by the fake Rolex people catchers...

    All the pumps are well pumps so have good suction, but as for mains water working 24/7, I am calling bullshit on that one, aint many places in Thailand that can keep the water running 24/7, I'd stick a tank in.

    Okay, I'll look at a tank too; any idea on cost? I didn't bother looking at Homepro, didn't think I needed one. The other houses I've noticed in the village didn't have tanks; maybe that's why everyone's water pressure is so shite...

    Go for 200/250 watt then or stick a restrictor in the washing machine feed.
