Wanting new water tank 2'000L

[Dieter78]

I'm interested in installing one or two 2'000L water tanks. I saw HomePro has sand stone finish tanks for 13'990.

Also i would prefer a different water level control than the standard buoy. I read about "Liquid level control switch".

And i would need a pump.

Can anyone offer advise on best place to aquire around Hua Hin?

Best to look around and compare prices. More likely to get a deal at Big Kiang if buying multiple tanks and they may be able to help with install if required. Check Watsadu etc and anywhere you seeselling the tanks as quite a few smaller places have them easily visible outside their shops. As regards the valve I have not seen any but have not really been looking either.

Water Tanks: Get the DOS brand tanks as their sides are quite thick and usually come with 20 year warrantee. At my home in Hua Hin I purchased a much less expensive tank that looked nice but the tank walls were too thin and light could shine through which promotes the growth of Algae (which happened). The Dos tanks are the best. You can find much better prices on them at places other than Home Pro. There is a large tile and plumbing supply place on on the left going to Cha Am near Thai Watsadu that has the Dos Tanks and with good prices on them.

Liquid Level Control Switch: Your stuck with the float valves unless you have a separate water pump that feeds the water tank. In that case you can put a floater switch on the tank that will automatically turn on the pump (to refill it) then turn off when it gets to a certain level. Two floating weights inside the tank pull the switch on and off. I have one of these on my water tanks as it turns the well pump on and off to refill the tanks.

If there is such a valve that you can substitute for the standard water tank float valve, I have not been able to find it as I would like one also. I have three 2,000 liter tanks. Two for well water and one for softened water for the house for which I have a separate pump and have to use a float valve for.

Thanks for the Tips! I will look for a DOS tank.

I started out with the same plan as you (2000 L tank), shopped at many many places. Ended up buying a 3000 L DOS at the place on the left as you drive towards Chaam, before Thai Watsadu. Paid roughly the same as many places wanted for a 2000 L and its foot print (size) isn't all that much more than a 2000 L. And they delivered to south end of town. If your budget and space permits, consider getting the bigger tank, it really helps get through the frequent dry spells when city water stops for a few days.

I found Home Pro cheapest in area, DOS COMM 001 S--2000L, Baht 8,490 Sandstone, ordered 19/04/2016 1 week wait, free delivery.
They also delivered 1" and 3/4" pipes at same time 4 meter wont fit into the Jazz.

Ran a feed from Pranburi water into tank through float valve, 3/4" pipe although all holes in tank are either 1" or 2".
Made a mistake by buying a 3/4" float, Home Pro have 3/4" to 1" brass adapter.

Not wanting to get into 2" pipe, bunged the 2" feed and 1" drain at base of tank. Drilled a hole in top of tank for 1" pipe for suction feed to original house pump.
Suction feed takes the constant high water pressure off the pump which I find prolongs it's life. Before the pressure diaphragm didn't last long, I have not had to repair it since changing to this system.

Add Baht 1,000/1,500 for pipes, valve, fittings, glue, paint brush, PTFE tape, and you have the kit for an enjoyable afternoon of doing what most Thai kids learn before they are 5 years old.

I have spare bungs as Watsadu only sold in packs of 5.

I would recommend proper pipe cutter which I am willing to lend along with trammel cutter if you decide to put in suction feed.

I now have original 2,000 tank fed from Pranburi for garden and can be filled with well water if required, this can also be fed to the house if needed.
The new 2,000 tank is purely for Pranburi water for the house, this is a great relief as often we were empty for days when the gardener/ pool man had used it all and there was no water supply.

"They also delivered 1" and 3/4" pipes at same time 4 meter wont fit into the Jazz."

Yes they can be carried by a JAZZ. I get 4m water pipes all the time and strap to outside of JAZZ. Run some straps over pipe and through the hand holds in interior ceiling just inside the two windows then roll up windows to tighten. Trick I learned from Pole Vaulters who had to carry there 15-17' poles to meets.

If you get in a pinch then just use towels or rags, wrap around pipe and pull through windows and close windows.

This trick works for 4 door ALL cars.

Also, DOS tanks should come with 1" float valve. Why mess around with smaller valves when it will take longer to fill with smaller valves. I would have junked the 3/4" stuff and done it with the right hardware up front. If not now then you will pay a price later so why not do it right and not have problems in future.

Yes, exactly. The tanks have an internal pipe from the base inlet up to the float valve. The suction should be taken from the bottom of the tank, but this is what happens when people believe that the pump has 4,000 psi pressure on it from the bottom of the tank!

There is no difference in the static pressure on the pump either way, in fact, it is slightly more taken from the top of the tank, plus the extra load on the pump with friction through the extra suction pipe fittings.

If you need a float switch Thai Watsadu have a sealed pear shaped float switch that can be wired either N.O. or N.C. to monitor either full or empty, or start or stop a pump. Or they can be used as a safety switch to stop a pump if the tank runs dry. Very simple to install and will never give any problems.

Just stating facts, the DOS tanks sold by Home pro have 3 clearly marked brass inset threaded holes. One 1" at the top marked inlet and 2 at the bottom on the other side 2" marked outlet and 1" marked drain.

Another fact, I do not take water from the top of the tank only from a 1" pipe inserted at the top which reaches to the bottom. Once primed this sets up a syphon controlled by the pump, as long as the tank doesn't run dry.
Thus there is no wear on the pump.

Another fact there is only the weight of 8 foot X 1" of water acting on the pump inlet.

Another fact mentioned before, this system has alleviated pump repairs, which used to happened often when taken from the bottom outlet.

The feed on to the property and into the house is 3/4" pipe, quite adequate, the differences come when you have a pump with 1" fittings and use the 2" bottom outlet.

As I said just stating FACTS that can not be criticized by any stretch of ignorance or a vivid imagination.

[Nereus]

Another fact there is only the weight of 8 foot X 1" of water acting on the pump inlet.

And the same FACT if the suction is taken from the bottom of the tank!

[chaspul]

Only the same as taking from an underground tank which most pumps are designed for. Another FACT.

[Dieter78]

I was at homepro again today and noticed they stock the liquid control switch!

[Nereus]

Only the same as taking from an underground tank which most pumps are designed for. Another FACT.

You just don't get it do you? Aren't you the same chaspul that claimed that your pump had 4,000 psi pressure on it from a tank?
And no, it is not the same as a suction from an underground tank. Having studied what I posted some time ago about shallow well pumps, you are now the expert.

The better quality tanks have all the inlets at the bottom, with an internal standpipe connected to the included float valve. SOME shallow well pumps(but not most) will give problems with a flooded suction, but having the suction taken from the top of the tank to the pump does NOT reduce the static pressure on the pump. Where do you think the water in the pipe goes to when the pump is stopped?

It STILL has very nearly the same static pressure on the suction as it does if connected to a tank. It fact, as I already posted, if you calculate it out EXACTLY, the pressure will be slightly higher doing it your way.

You do what best suits you, but if you are going to come on here with stupid comments, then expect to be ridiculed.
More so when you post comments like the following:

As I said just stating FACTS that can not be criticized by any stretch of ignorance or a vivid imagination.

Oh my. "Just stating the FACTS" Guys, lets try to be helpful and not negative!

[dalmatiandave]

Yes this swinging dicks bravado is a bit tedious. Sorry what are we discussing here, oh yes, a water tank. God forbid you guys fancy the same bird!
