Instalation Of 1000 Ltr Water Tank And Pump.

[nong38]

I have just had a bath built into the house, but the water pressure is not good, I am told I will need a water tank, they seem to be about 8000bts down at Home Mart and a water pump which is also at Home Mart for about 7000 bts ( Mitsubishi ). I f I get these home and then a man who "knows how to instal" these items and make sure it works, how much should I allow? I am guessing the water Tank and pumps will be outside but under cover ( ground level ) also the bath will be on the same level. I am not in Bangkok but Nakhon Sawan if that helps, I prseume things are bit more expensive there. Any figures to work with would be helpful, thanks.

I havn't checked price on tanks/pumps lately, but those seem a bit on the high side. (?) If you don't want to DIY why not check out some of the local places for a package deal? Otherwise, IF it's a simple connection, hooking up shouldn't take more than a few hours (1 day TIT) and that shouldn't cost more than B500 for labor.

BTW: You might consider a 1500 liter tank and a 250-280W pump for what I think is good for the "normal" Thai home.

Thanks for that information, one istaller is talking 3600 bts, I guess that because I am a farang?

Global House in Nakhon Sawan have everything you need. Pump we bought recently was 4300 baht and the 1000 litre tank about the same. However, there are many designs for tanks and materials, so there is a huge choice. Further back the bypass on the same side is another building supplies unit and they also have a lot of tanks on display. I did ours and it cost about 1000 baht in materials, but that included valves and Tees and bends as I wanted a bypass arrangement. If the guy is supplying the material, 3600 would be OK, especially if he does it regularly.

Getting a 1500 ltr storage tank and a Mitsubishi pump was one of the the best investments I made in Thailand.

Whatever he charges just make sure the switches are in a convenient place within the house, I installed my myself with a switch upstairs and a switch downstairs. K

Switch for what? The system should be automatic so other than normal on/off breaker no switching should be required - using normal float valve to fill tank and water pump to operate on demand. So beyond the tank/pump only a float valve (and bypass/one way if you want to allow for automatic electric outage bypass or just taps for manual) and pipes. Expect 500 baht for work would be reasonable but if foundations have to be made for pump and tank then the 3-4k figure might be reasonable (including parts).

My pump prime itself every 2 mins when switched on, the water from the mains pressure is enough except at night after 10 o/c so hence the switches.

Am I correct in assuming you have a permanent bypass in the system, from the mains water incomer to the house supply, fitted with a non-return valve so that isolating the pump allows you to use mains water pressure?

[JeffreyMcCollum]

The pump should have it's own circut breaker, and wire run, That alone will cost over 1000 Bt. Then depending how close or far the tank is, lines, fitting, float valve, check valve, etc, 3500 seems closer to right to me. for NS

[wayned]

I live in NS province, in the boonies. I have a Mitsubishi WP255Q3 WP that delivers 40 psi. I bought it a few years ago at Big C for 6300 baht, so 7000 today doesn't seem unreasonable. Others are available for less than 5000 baht but with lower water pressure. I have a 1000 liter tank but it's 12 years old. Installation is simple and if you are a DIY guy very easy. Three inline cutoff valves, pvc pipe, a flow control valve, drain valve, float valve and fittings. Should cost about 1200 baht. You need a good foundation for the water tank. the full tank will weigh about 1200 kilograms. Also you should have the pump wired to its own circuit breaker. I have mine plugged into a switchable outlet so that I can turn it off when we have "brownouts", the pump doesn't like low voltage and where I live we have a lot of them. If the guy is going to supply all of the parts, knows what he is doing and install it for 3500 baht it's not unreasonable.

Hi Guys can you tell me what is the biggest tank capacity you can get in thailand

Cheers

We have a 1500 ltr tank and it lasts about 4 - 5 days if there is no water, I've seen 2000 ltr tanks don't know if there are bigger ones but you can always link two three and so on.

We don't have a tank/pump, only being two of us we can cope, but the neighbours both sides do have. We can hear their pump, albeit quietly, when it switches on, but theirs does not seem to prime every 2 mins. In fact, when they are out you do not hear the pump at all. I wondered if your had a leak or a faulty non-return valve in your system causing your frequent pump starts....just a thought...

I know quite a bit about building but when it comes to plumbing, nothing seems to work out for me , as I said we have mains pressure that varies very much and no water at all from the main after around 10 o/c, you may be right about the non-return valve we are not inconvienanced by switching the pump on and off when we want it.

I know I have got one of the cheap brass one which just has a flap, I will source a better quality one, what I want as well is to find a decent stop-cock for the tank it does always shut completly and the tank overflows.

Any plummers here.
