Water Tank and Pump

[Robert54]

I am living in rural Isaan and am looking into getting a water tank and pump.  I have a few questions.  Apologies for my lack of knowledge... 

 

1.  If I install a tank and pump at my house, will it affect the water supply of my neighbors? 

2.  How does the process work exactly?  Does the city water fill up the tank and then I pump it out?  Or do I need to pump it into the tank and out of it also?  

3.  Estimates on total cost of a 1,000 liter tank and pump.  (We only have water on the bottom story of our house.)

 

Thanks for the help.

Moving this to the do it yourself forum. You questions are not specific to Isaan.

1. No

 

2. Normally, the tank will be plumbed in so it fills with the your local  mains water supplier. Some people do have their own bore hole, but this can be quite expensive to do. The pump is then positioned between the tank and the house. The tank has a ball valve type arrangement, similar to a toilet cistern inside which will cut off the water when the tank is full.

 

3. A 1000 liter tank will cost between 6,000 to 8,000 baht for one that has a good grade interior. Don't buy one of the cheaper blue plastic ones, they will just get green algae growing on the inside over time. The pumps will be between 5,000 to 7000 depending on what wattage you require.

Hook it up like this:-

 

 

And you're good to go.

 

The non-return valve at the bottom ensure you have city water if the power is off or the pump fails.

 

These valves can seep if they get a bit of muck on the seat, so either use two or drop a regular valve in its place, normally leave off, just turn on if you need city water pressure.

Thank you.  That is very helpful.

Would you want an on/off valve on the direct pipe from meter to house supply?

If you don't trust the non-return valve, then, as Crossy said, use a normal valve instead.

Yes, in case of a problem with the pipes in the house.

There's a limit on how much detail to add.

 

Yes you would want a supply stop but there's invariably one at the meter, we also have one at our incoming filter (so I don't have to walk to the meter).
