Cheap water tank and pump?

wouldn't go cheap, you're asking for issues, for somethings it's better to pay for quality, but, up to you.

Chinese got in the meantime same quality but better prices

  • You’ll want at least a 350 watt pump for most plumbing configurations and depending how far the shower is from the pump, anything less than that probably won’t provide the “Western pleasures” for you 

  • Then something is wrong, 350w pump will do a 3/4 story....

    Divide that 140 - 180 bar by 100 and you will be good.

No, it was you, go look first page at 22 hours ago, it got 3 laughs, one was me.............🤥.............🤭

 

Now I hope the information I have posted has set you straight on the subject.....😉

I can't find anything talking about a 350w pump or similar. It's definitely not me. I strongly suggest you've mistaken me.

All these pumps provide I think provide 11.5 PSI, the wattage comes in regarding distance and elevation, pipe size will also play its part......

This  is what I go  by.

Memory wasn't quite right, 140/180 is the smaller pumps and 200-220/260-280  for the larger.

A higher discarge capacity is required to maintain flow in the face of restrictions, which would include distance,  additional elevation, piping, small diameter outlets etc. The nominal  output allows for a certain amount of elevation.

The output pressure on the 100 range is a bit less but the larger sizes are all the same pressure, if I remember right 140 - 180 bar.

The flow at outlets is a different thing altogether, dependent on restrictions and demand on the pump.

On the basis that only one outlet is on at a time a 250 pump should be adequate in a bungalow, mine certainly is, but a higher floor would probably need a 350 pump.

I have a 100 pump for watering the garden,  that sucks up about 6 metres from the well and with only a hose gives a very good jet of water.

All about system load on the pump.

I am always good,  but what has that got to do with pressure switches.

You quoted the pump pressure at 140 to 180 bar which is 100 times what it should be.

Appears you are not good ….. at maths !!

350w is as low as I can go and it’s barely just enough. 

yeah iam running a mitsu 300w pump and it is barely adequate for my single story 3 bath house.

 

Tank (under ground 5000lt) to house entry point is approx 40m.

It may come as a surprise to you but "on demand " water pumps are controlled by a pressure switch. With all outlets closed the pressure in the system would fluctuate between the pressure switch limits, which for a 100 watt pump  would be 140  - 180 bar. Larger pumps have higher pressure switch limits.

You may well be good at maths but obviously not water pumps. Do you really believe that atmospheric pressure could supply water to a domestic dwelling.

So you are saying that the household pumps we fit here in Thailand can reach 2000 to 2600 psi ??

 

Dream on “ water pump expert “ 😂

Apologies, I had thought the switches I had changed were marked  in "bar" ,  but on checking I see it is kpa.

Admittedly much lower, but if you had known anything about pumps you would have realised the mistake rather than making an unwarranted derrogatory comment. After all I did ask you how your comment related to  pressure switches, to which you replied

"You quoted the pump pressure at 140 to 180 bar which is 100 times what it should be.

Apologies I saw your mistake and just went with it.

I used to be a nice guy until i joined this forum !

The OP should ask the landlord first. They may agree to the tank and pump installation and do it at their cost and their responsibility. They may also have a cow about the tenant doing it, including claims for consequential damage. Or, they could flat refuse, which would mean looking for new digs.

Yes, a common trait. 

I  don't have the luxury of mains water and have 16 years experience of maintaining 8 water pumps of various types. One thing I have picked up along the way is that when shopping for parts it is the numbers that count, units are an unnecessary distraction, so why try and remember them. At my age, remembering what happened yesterday is more of a priority.

Don’t know why you continue to defend yourself, you were wrong just leave it at that.

“Units are an unnecessary distraction “ what utter rubbish !!

If you quote the wrong units you will get the wrong result.

You mistakenly quoted the wrong units and I apologised for being too harsh but now you are just digging a bigger hole.

You are wrong to think that in a practical environment that the theory prevails.

I am more than happy that I don't need to run to a repair shop  when something goes wrong.

Small punp switches are marked 140-180, which is what I said, and all the shopkeeper needs to know.

Your air of superiority is doing you no favours.

You wrote 140-180 bar, which is totally wrong.

Air of superiority is present in every post you have ever written on this forum.

Seriously doubt 140-180 bar for any domestic pump. Those pressure are power station boiler feed water pump pressures.

Big difference between kPa and bar.

Nonsense.

Rubbish. I can feed all my showers, sinks and outside taps using just a 250 watt pump. Just ensure you only use two of those listed at the same time.

Why would you need a heater on your mains water supply?

Sure, you are content with “adequate” water volume/pressure and I’m not.

How many outlets are being used via your pump when you do shower?

On 8/10/2025 at 1:00 PM, tuk75 said:

500 l tank from 1700 bath at Lazada

Water pump 800 - 4000 bath Lazada

We use a shower, not a Bath.

Ask Hummin, he mentioned it.

Well that depends on how many outlets are being used while the shower is being used, goofy question you got there.

Then why ask me, you seem disoriented.

Matched by an equally goofy answer.

It was Hummin who mentioned the heater, not me. I was answering your question with a sensible response.
