Hello,

Does anyone know if bladder type water tanks are sold here? I know about the storage tanks but can't find bladder tanks.

Thanks

Don't know if thats what their called. The bladder tank as I know it is a tank with a rubber diaphram that sits near the top of the tank with an air charge in it. It helps prevent the water pump from cycling too often.

I think I have installed what you are looking for. The local Independent Thai "Pump and tool" shop called it a "Pressure Tank" and it is available in various sizes. We have a SWK brand 500 liter 2mm pressure tank with a Square D brand controller switch model 9012 FSG-2. There is information on this Square D product that is made in Italy on the internet. I could not find information on the SWK tank via a quick Google search.

Once this "pressure tank" was installed by the shop technicians the Hitachi Inverter pump was activate FAR less. In my opinion it saves NOISE, ELECTRICAL USAGE and wear and tear on the Hitachi water pump. We immediately had significant water pressure in the second floor bathrooms to activate the Stiebel Eltron under counter multiple point water heaters.

WARNING: About two days after the first usage of the pressure tank we had some leaks in the bathroom plumbing near the sinks and/or toilets. The builder came and promptly fixed this situation and I noticed they used CHANG brand glue on the PVC pipes for this repair. They have not leaked since and I was told the water pressure became far higher in our pipes than "normal" Thai construction once the pressure tank was activated. The SYLER pipes did not have problems, only the PVC thick walled pipes.

I was given a one year "parts and labor" guarantee by the local Pump Shop in Buriram. Handy since the Square D 9012 FSG-2 had to be replaced and twice they have made adjustments to the pressure tank. Seems to me there might be an adjustment switch on top of the Square D switch. But WITHOUT this "pressure tank" we would have to have the water pump operate 100% of the time we use water in our home.

There must be a scientific formula for how much water pressure you obtain via gravity and a water tank installed high. In our case we did not want a "tank in the sky" and I was told by the builder and pump shop that for water to be sufficient pressure on the 2nd floor of our home we could A) use the pump only or have the pressure tank to minimize the pump usage. From our experience the pressure tank was well worth the money.

I believe that is what I'm looking for. Thanks for the pictures. I went to the local Home Hub in Ubon and the salesmen had no clue what I was talking about. I'll show him the pictures.

Thanks

In Ubon if it is anything like Buriram Province I think you will have a much better solution to our water supply / water pressure situation if you deal with a "pump and tank" specialist. It might in fact cost you less money than a "modern trade" store. I have consistently obtained LOWER prices and top flight service from a BUSY shop that supplies the materials and labor to install, upgrade and repair the water supplies for dozens of not hundreds of the surrounding villages. This same shop installs the water tanks, pumps and items for hospitals and hotels. In my limited experience with Home Pro I was not filled with confidence in the product knowledge of the staff. Home HUB might be a different situation. My point is that every province must have at least one "specialist" shop that has years of experience installing and/or selling solutions to water supply problems.

The pumps they sell here in Thailand have a build in pressure reservoir it is small but mine works for years allready,the ting is when you installed the pump and you start it up for the first time run it with the dischargevalve closed so the air inside got trapped and pressurerised,when the pump run out of water it,you have to repeat the procedure you will notice because it will start and stop every 10 seconds.This way you will save yourself a lot of money.

If you are in Udon Thani and go to Homemart ask for mr.King he has been living in Australie and speaks perfect english.

Big apologies guys if this is a stupid question but when you say: your "pump was active far less" (kamalabob2) and "It helps prevent the water pump from cycling too often." (TPUBON) are you refering to your water pumps 'working' when there is no water being used in your system?

As you might have guessed I can hear my water pump working but nobody is using any water.

[kamalabob2]

I was given a choice at initial installation. a) Not have a "pressure tank" and see how often the Hitachi pump cycles on

or spend the 5000 baht and purchase a 500 liter pressure tank.

In our case we did NOT have a pressure tank initially and 100% of the time a faucet or water tap was operated the Hitachi water pump went on to maintain water pressure in our home. The pump came on even if we filled a glass of water or washed out hands.

So I spent the 5000 baht and had the local "Pump/tool/tank" shop install the SWK brand pressure tank with Square D controller switch and NOW the Hitachi water tank only goes on perhaps six times each day. This is a significant difference. Our water storage tanks are at ground level, not up the required height to have gravity help with water pressure.

Note: The local pump shop guaranteed the pressure tank and installation would solve our problem of the water pump being activated with EVERY water usage and we are 100% satisfied and did not have to take the merchant up on his "money back if no work to fix problem" guarantee. I knew NOTHING about pressure or bladder tanks, I came to him with the mandate to obtain adequate water pressure in a two story home WITHOUT running up the electric bill via a pump activating 100% of the time. He understood that mandate and suggested and implemented a solution without running up a large bill or getting a series of "no can do" type answers that sometimes come in Thailand when you ask for a solution. I've been a guest at Farang built homes and it amazed me that electricity was used and you hear pump noise 100% of the time you ran water inside a home.

The Mitsubishi water pump we use to pump water from the PWA pipes into our 4 stage filter system after which the water then flows into the two 2000 liter clean water storage tanks is activated about six times a day to maintain a volume (depending on water usage) in the storage tanks via "RADAR BRAND electronic controller" which costs around 250 baht. In our previous rental we initially only had a "ball float" in the water storage tank and the water pump was activated dozens of times each day PRIOR to installing the "RADAR BRAND electronic controller" for the storage tank. I've seen similar, just slightly more expensive controllers at Home Works.

If you work with a good pump shop you can minimize your electrical usage, noise, and wear and tear on your water pump(s) and still maintain great water pressure in a one or two story home with minor initial investment which will more than pay off in the savings of a lower electric bill and the extended lifespan of your water pump(s).

The Pictures are awesome! Thanks.

Just wondering if I'm going to have water tank and water pump problems in the future.

I just purchase a semi detached 2 level home in Nonthaburi (Bang Bua Thong district) and I have not a clue about their water supply.

In addition, with little research and lack of salesman help at Home Works and Home Pro, I went and bought a 750 litre "Jumbo brand" nano tank (above ground) and a Hitachi WT-P200GP water pump. I have two Fujika water heaters (one upstairs and one downstairs).

I don't expect the water pressure or temperature to be equivalent as to my New York apartment but I'm hoping this will do.

I don't know if I'll need a pressure tank though. Any advise you can give is greatly appreciated.

You shouldn't need a pressure tank as the Hitachi has a small one built in

Make sure you are pumping from the tank not the main, mains water should flow into the tank via a float valve. Ensure you have isolation valves so you can service the pump without losing water.

You may also wish to install a bypass using a 1 way valve so that if the pump fails you can use mains water pressure direct.

For a domestic water supply there are a number of options.

1. overhead tank to keep the house pressure at a usable pressure - this usually requires a pump to keep the tank filled.

2. a pressure pump - Hitachi / Panasonic with its own built in pressure tank - problem with arrangement is that the air in the tank is gradually replaced by water and the pump when hunts on and off with the slightest leak anywhere in the system.

3. a standard motor pump pumping to a bladder / diaphragm tank which has the air cushion separated from the water by a rubber diaphragm or fitted with an air bladder. This type of tank for a domestic installation doesn't need to be over large as it's use it to make up for any minor leaks or a couple of quick turn-on’s of the tap etc before the pump kicks in to jack the tank back up to its preset pressure.

4. There are also flow sensing system available which start up on a drop of pressure such as opening a tap, the pump then runs while every there is demand and shuts down once the flow is stopped.

For simplicity I believe that the bladder / diaphragm is the best option to a home situation - easy to set up and gives long life - you only need to monitor the air pressure in the tank on an infrequent basis or if you think the pump is starting / stopping too often.
