I'm thinking of installing a 'Lucky Star' brand deep water well pump system. With this system no large storage tank is needed. The well (bore hole) will be 30 meters deep and have a 2" pipe. Inside the pipe are 2 smaller pipes for water pickup. Anyway that's the diagram I was given. This system works using air pressure and I've seen a working version and it seems to work okay.

My question: anyone here have a setup of this kind or something similar? I've only found one other company that makes this type of pump with the hookup necessary for the 2 tubes inside the larger tube; that was Hitachi.

Who makes Lucky Star? Chinese I suspect or maybe Thai made? It comes with a 7 year warranty; I was wondering if it will be reliable.

Any input on this appreciated. I started to put this in the Farming Forum but it's not for farming just home water supply.

Thanks.

I think it may be Korean. If it is related to the Lucky pro model. They only offer a 1 year warranty,if it is the same company.

I was going to add the lucky pro to a 2000 liter tank till I found out the sales guy at Home Pro was off by 2 years, he said it was a 3 year guarantee, it is only a one year. I would inquire about that-if it is a Chinese made model , they are throw away items, usually tough to find parts for. I think on a Google search last night I did see a lucky star deep well pump from the yangazee co. or some name similar out of China.

I am looking for a Mitsubishi or Hitachi now so I won't have to replace it in 1 year & 1 day when the warranty goes out.

good luck!

edit strike the warranty comments . if you got a 7 year warranty it probably isn't a Chinese made pump. They are a no-1 year at tops usually.

The Lucky Star has a sticker on the front (written in Thai) with a '7' on it. I asked the wife what that was and she said, "it's the warranty, 7 years". On the Hitachi the warranty is 5 years. This is at the Global House in Udon Thani.

Lucky Star costs 7,180 baht

Hitachi costs 7,990

According to the 'specs' on the 2 pumps the Lucky Star seems to be a little more powerful. I'm worried about buying a brand name I don't know

hi,ive got the same lucky star pump model LSC 250 EA had it 2 years we had a government well on our land,when they moved it further down the village,they just left the bore hole open about 5inch diameter,id seen the lucky star in action and liked its pressure,think i payed 7000 baht for it,so me n the father in law set it up dual pipe 30 metres,my furthest tap is around 15 metres away,the pressure nearly blows your hand off on full,in the 2 years i had it,it as burned out once cause we had it running all day,the father got it repaired for around 500 baht,last week it was leaking underneath when we had alook it had rusted a small hole because there was no air flow underneath it so make sure it is off the ground so the condensation on the tank can evapurate once again the father got it repaired for around 200 baht,my oppinion its been a great pump its also very quiet...well pleased with-it they actually stock all the spare parts for them as well incase as i found out at the hardwear shop where i purchased...

oh i forgot to mention the reason i bought it,there was a well drilling company in my village a few years back installing these at atleast 10 houses mostly falangs over the last 3 years ive heard of no complaints from any of them....

MrJay, thanks this is exactly the reply I was hoping for. LSC 250 EA is the exact model I looked at. The Hitachi model comes with a stainless tank so maybe that's why it's more expensive. Also the Hitachi model is rated at 300 watts while the Lucky Star at 250 watts. Wonder if there is any advantage/disadvantage there for one model over the other?

BTW, any idea who makes the Lucky Star?

Thanks again.

I've had a lucky star deep well pump for 5 yrs now and have had a couple of problems....the impeller wore out due to sand in the newly dug well [blame the well, not the pump.

then the steel tank developed a leak and i replaced it with a stainless tank. otherwise it has been a good pump and does put out much more pressure than my hitachi shallow well pump.

This is the second report of the tank on the Lucky Star developing a leak; not a good thing.

Undecided now on which pump, decisions, decisions.

I did on online search with Ixquick & Google for hours & could not find anyone listing where the pump comes from. I am in the same boat as you . Still looking. I know the Mitsubishi line & Hitachi usually do not have problems. I really like my 300watt Mitsubishi. too bad I added the water tank & need a second one to drive the tank to the house.

I think sand or iron would give hel_l to any pump regardless..... Global house must be one of the few carriers of the Lucky star.

I couldn't find any of that brand in Pattaya to check out the origin. Pattaya has no Global house stores.

As a pump engineer with over 30 years experience, my recommendation is to go for quality with your deepwell pump, it might cost you a bit more up-front but at least you will sleep at night not worrying about it. Hitachi or Mitsubishi would be worth the expense which in real terms is not that expensive anyway.

The system you need for a 30 metre well is commonly called a 2 pipe system which is installed within the well casing - one pipe is used to transport high pressure water to an eductor located below water level in the well - the eductor entrains the inflow to the well and the combined flow is transported back to ground level - in effect you might pump 2 -3 gallons down the drive pipe and return 4-6 gallons up the return pipe usually to a holding tank which is also the water source for the drive side of the unit. Fairly simple and straight forward pumping operation although not all that efficient in terms of power consumption, an electric submersible well pump will be more efficient and in the long-run may be a better option.

Let me know if yuou need any further info.

Which even system you use, any sand passing thru the well screen into the well and into the pump is the killer - where ever possible use stainless steel or bronze for the pump parts.

Have a look at the following link - this shows you a 2 pipe well system - the same for all brands.

Artisi, thanks for the link it explains things so even a layman like myself can understand.

The bore-hole has been dug in the wife's village and the twin-system pipes installed so everyone is waiting on me to bring the pump. Looks like I'll go with the Lucky Star as parts seem to be carried in stock. Some of the Lucky Star tanks are rusting out but they can just be replaced with a stainless steel one. The jet pump system seems to be a little simpler and the one I have seen in action was working great and putting out plenty of pressure.

I am 99% sure my deep well pump is a Lucky Star, had No problems so far in a Year of use.

Make sure you get the deep well configuration not the shallow well type - there is a difference between the 2.

Hello Artisi, I have recently installed an LSC-250 EA to my house in Phuket with disapointing results.

The water pressure supplied to the upstairs bathrooms was never good from day one, with the water reducing to a trickle while waiting for the pump to kick in and do its thing.

If i was to crack a garden tap close to the pump the water preussure although not brilliant is ok,with the pump cuting in and out at regular intervals as advertised.

so i have 2 questions for you, first it appears that demand further away from the pressure switch and the delay in the the switch sensing the pressure drop could be the main reason for the poor water supply?

2nd, What effect takes place if i had a leak at the air charging valve and is there anyway to recharge or even check for air pressure at the pump?

Other info> Im drawing from a 15m well, about 6m across the ground then up another 4m to the upstairs bathrooms with no header tank installed.

Any info or advice you could give me would be much appreciated.

I had one installed five years ago and it's run faultlessly with no attention whatsoever. It supplies instant water pressure to my two houses which are 150 metres apart.

It's so miraculous I even mention it in my book about living in Thailand.

Everything else breaks down on a regular basis!

Hi Andrew, Any idea of how deep a well your pumping from? And is that right, your supplying 2 houses with good water supply with just one of these luckystar pumps?

Cheers!

Dirk....

I had the same deep water well pump installed on a 35m well recently and the pressure is a thing of wonder. Nice quiet pump too.

I had a borehole drilled 2 years ago and they fitted a Luckystar LSC-251EA. (Booklet that comes with it printed in Korea, so probably manufactured there)

Overall it seems quite good but about 6 months ago the tank developed a leak. Seems like this may be a common problem.

The installer came out and it was repaired at a cost of 500 Baht. I queried about the guarantee, but was told that only covered the motor. I was also given the choice of replacing the tank for 2,500 Baht. This seemed rather expensive to me.

Now it is leaking again. Not as bad as before, but obviously I need to get it sorted out.

There is a Global House in Khon Kaen, about 30 KM from here. Does anyone know if they carry a range of spare parts for this brand? I see that a few have mentioned getting a stainless steel tank and wondered at the cost and if will last longer.

It seems pointless to spend 2,500 Baht for a new tank if it is only going to leak again in 18 months time.

Other than that, maybe I should consider replacing it with an Hitachi.

Apart from the leaks I am quite happy with the performance of this pump. It gives a healthy water flow despite the installers only using half inch pipe from the pump and it's quite a long run to the house.

Does anyone know if it is possible to actually reduce the pressure a little. The water flow does tend to pulse when using the shower unless I open another tap slightly.

Any advice would be much appreciated.

Since I had my lucky star instaled it has run well with no problems. Soon after I fitted an additional Hitachi which has failed once, I just replaced the whole pump and then stripped the old one down slow time and identified the fault so I just have to get a new part (no idea where from) and I will have a working spare. Strange though I assumed the Hitachi would be better quality, maybe just bad luck though. Just FYI.
