power pump for water

Post by **hurm** » Mon Jul 20, 2009 6:58 pm

hello there,
As it takes an hour to get my shampoo out of my hair I am planning to install a waterpump for my 2 story house and at the same time a chalk filter as all the taps and heaters are bad working due to chalk. Is it handy to install it close to the watermeter? I have to get electricity overthere as well, I suppose. any idea about costs?

you should place it as near to the water outlets as possible.this will maximise the pressure. try and put it under some protection also, as they are pretty cheap things, and are best kept away from the elements.

Perhaps best to bring the city or well water into a tank first, then tank out to your pump, and pump in to your house.

I've never heard of hooking a pump directly up to a city or bore water line for a boost into the house. There really needs to be a holding tank in between.

As SL says, get your tank and pump as close to the house as you can, hopefully in an area that doesn't ruin the looks of your place. The pump should have some kind of cover over it to protect from the elements, not just the lid that comes with the pump.

Perhaps someone can take a photo of a simple system in the AM for your reference. I can't as tank outside and pump inside a pool filter room. Pete

okay thats possible, but a watertank between pump and meter is not possible, no room. In our compound I saw single waterpumps so I thought it was possible without the tank. Maybe they have an underground tank....

So now I am in doubt what to do, there realy is no possibility to keep a watertank out of sight (lots of terrace, small pieces of lawn surroundig it). and a chalk filter in between pump and meter?

Hurm, you're putting vinegar into your pool but no room for a tank and pump? Yes and OK, many houses have underground tanks.

The tank doesn't have to be anywhere near the meter, you can put it on the furthest end of your property. The tank is filled by the natural pressure from the city water pipe. From the tank into your house is then pressured by your pump.

The distance from your pump to your house can be controlled by the size/power of the pump you buy. Many grades are available. Pete

Our posts crossed, sorry. Above I was responding to your reply to SL.

You don't need to keep a tank out of sight. There are above ground composite/plastic/nylon tanks that come in many colors and even etchings of landscapes on the side that if visible look attractive. They'll also last years longer than the shiny chrome/whatever over steel tanks you see in many places.

You could dig a hole for an underground tank. More expense but out of the way. About 1 1/2 meters deep with screw on cover. 1,500 or 2,000 liters is the norm. You can landscape around the lid so people won't even know it's there.

Chalk filter I'll pass a no experience.

Khun Nereus, are you here? Hurm, he knows a lot about this stuff. We'll try to get you through this. Stay tuned tomorrow. Pete

Are you using water from the municipal supply or does it come from a well ?
First check the obvious before looking to install a tank or booster pump - the pipes or shower hoses could be blocked by small stones or grit as can the filters on the shower head or heater inlet pipe - especially if there's building work.

Having a tank might help if the outlet is not at the lowest point as it may allow for some of the impurities to settle at the bottom of the tank.
If all else fails you'll probably have to go for a water filter and softener set-up - Home Pro have several models but you'll need to regularly replace the cartridge or filter medium for it to remain effective.

Underground tank 2000l are 12-13k for the fibreglass ones .Plastic ones about half that but I know quite a few people that have had problems with them . .Make sure its installed properly and not just buried as it will implode . If you have it done then post some pics ,plenty of posters on here to tell you if it's being done correctly .Above ground tanks take up space and are pretty ugly in the main but you can get decorative ones .They are easier to clean and you have the advantage of a little head which gives enough pressure for a wash in the event of a power outage .

the water is coming from the munnicipal supply and yes, there are small stones all the time (chalk pieces in the shower heads, heaters and kitchen tap).

the water is coming from the munnicipal supply. And yes, little pieces of chalk every week in taps and showerheads and heaters as well. My house is situated on a point, so a little front garden in full view, left and right 1 meter terrace and a small piece of lawn running along the terrace and the backyard is all pool and terrace. So if a pump without a tank is not possible, I have to burry it in the front garden.

you are all very helpfull. Maybe I should take a look at Big Kiang? I heard they have a lot of experience and a lot of tanks and pumps. On this forum people are not very pleased with machinery delivered by homepro. I asked a Thai guy last time what the best powerpumps were and he answered a Mitsubishi and always take for a floor more then you actually have (he uses them in his guesthouse).
But I still do not know why it is not possible to connect the pump directly on my watersupply and why here should be a tank in between. Because everybody has it? I am not a technical bright head but I want to understand how things are working. In the local paper I read that Hua Hin is building 2 huge water reservoirs to avoid water shortage in the future, so the tank would just a temporarily thing......

I don't have an answer to that and you're right in that everyone does it so there must be a reason?

The pipe coming in to your property from the meter is 1" at most. It's possible I guess that with no bulk supply of water behind it, the pump simply can't suck enough water out of a 1" pipe to give you any better pressure than you have now. This is just thinking out loud.

Possibly it could also suck so much, none of your neighbors would get any supply at all while your pump was running.

Someone on here must know the technical answer. Pete

If the water pressure is insufficient it may help to install a booster pump but one must also consider the size of the piping especially if it is a large two story house. One inch pips restricts the flow and it might not help by installing a larger pump with a higher capacity if the water pressure at the outlets are still insufficient. The flow rate is often the limiting factor.

A large house should be fitted with a minimum size of 1 1/2 inch pipes and sometimes even 2 inch might be required.
