I am going to place this in a couple of forums, but the farming forum is usually so helpful and knowledgeable I hope someone out there can help me. I need help. I have a water tank that is not quite high enough to supply water pressure to my upstairs shower. It would be very expensive and difficult to raise the tower the extra metre or so it should be at so I figured maybe I could install some sort of booster pump to raise the pressure. The pump doesn’t have to pump water (it will flow into it from the water tower) it just has to boost the pressure. Has anyone heard or know of a pump that is designed for this and where would I get it. Thanks in advance I’m sick of waiting for my bucket to fill up with hot water so I can have a bucket shower.

When I installed a hot water shower, I discovered that the tower did NOT supply enough pressure to trip the pressure switch in the shower unit, thus no hot water. I didn't look for any type of special pump. I bought a normal water pump and it works great. Just pipe the pump inlet to the tower and the outlet to the house. I think I paid about 4,500 baht for the pump. Any of the super stores will have pumps. I bought mine in our small village. They had three different sizes. I bought the middle sized one and it has been working great for more than three years. It's an easy installation using plastic pipe and pipe glue.

i guess you did not buy a "normal" water pump Gary but one of the package units containing pump, small pressure tank and a pressure switch for house water supply. a normal pump would be much cheaper but wouldn't do the job (pump running and increasing pressure only when there is demand).

cheapest units (200watts) i have seen a couple of years ago in Tesco for ~3,000 Baht.

My pump is one of the common self contained units, pump, pressure tank and pressure switch. I looked at pumps with the tiny little nitrogen charged tanks but they run too often, cycling on and off every couple of seconds when a tap is opened.

Yes Gary the ordinary household pressure pump system is the go, the mains pressure was so poor at our house in Udon we had it hooked up to suck our water from the mains and deliver it to the house.

I now use them as irrigation pumps to draw water from the ponds,they do a great job.

Issangeorge, go for the mid size if you are going to mount it at ground level as their pressure head is not all that good,but if you mount it on the tower at tank base level you will get away with the small model.

The small one is 1/2" outlet and the midsize is 3/4".

A pump will only raise water 1 atmosphere (32 feet) could that be the problem?

the OP doesn't have the problem what you described (sucking from the ground) but pumping it up. for pressure and height pumping up water or any liquid there is virtually no physical limit if the pump is designed and powered accordingly. it is however correct that a normal pump can not pump by suction from a depth that exceed 10 meters. the latter value varies depending on height above or below sea level (different atmospheric pressure).

Thanks guys, an ordinary water pump was my original idea, but I was not sure if it would work win it had a small pressure fill going into it. I saw this on the web and thought maybe it would be the best bet, but I don't know if one can find them in Thailand. http://www.pressurebooster.com/ plus they are pricey. Issangeorge

Yes but that's still just a pump, albeit a slight bit more fancy. Why bother when you can get what you need cheaply and easily? And the thai ones come with a cover.

My household pump draws water from underground tanks, and there is still plenty of pressure for a good shower upstairs. In fact I regulated it back a bit as I feared for the plastic household piping :o
