Water Supply For Dummies

[philo]

My wifes house is fed from the village's water tower, so the water pressure supply is ok where her water tube is connected through the meter at the roadside. Also, the 50 m. feed tube to the house (I think it is 2 inches in diameter) is ok. The 'craftsmen' that built the house did stupidly connect 3 sinks, 2 toilets and to showers/waterheaters in SERIES with the standard (1 inch?) blue tube. So if you open the water in the kitchen, the pressure in the bathroom is so low that the shower unit turns off the heater.

By openeing and closing outlets I have been able to detect the connection sequence from room to room and outlet to outlet. The only way to fix this situation permanently is to open 2 walls, cut the tubes, and have the three resulting sections fed separately from the 2 inch tube. The first section is already fed, and needs only to have the tube closed. The second and third section must be fed from tubes following the house's outer walls to the place where the 2 inch tube can be cut and an 'distributor' be made.

My wife will not do this. Instead she has bought a water tank (ECO JAZZ ECM 550 from Homemart) and a pump (YESER YS-TG130 0.37kW/0.5HP, max head 30m., max suct 9m.) This is to be installed on a tower about 3 m. high.

Obviously the tank will solve the problem that they often cut the water supply to the willage, so we cannot even flush the toilets without keeping buckets of water.

But will it solve the pressure problem? With a relatively high water pressure from the road, I guess that no pump is needed to feed the tank, so the pump she has bought is supposed to be at the tank outlet? I am totally blank, and she will not get people from outside come and do it. Instead she will let her father and brothers (who are cluless) do it. That way the money stays in the family (sic).

I am shure they will fail, so could anybody give me a primer on this topic. Thanks.

EDIT I forgot to say that the tank and the pump will be about 20 m. from the house. Does this have any significance?

Look at the following link - posting No 8 from Crossy shows how to connect your pump.

Thanks. I found this tread : http://www.thaivisa.com/forum/Connect-Wate....html&st=25.

So I guess we need to tanks: one for just filling up when the water supply is coming, and one after the pump (the presssure tank) to feed the house.

I have printed out Crossy's diagram, and will show it to them. Hopfully we will be able to find a solution.

Thanks again.

The pump will not solve the problem unless you run a separate line to your bathroom. That should not be too difficult. We had a similar problem and only the bathroom receives water from the pump. Our village only has water twice a day, a couple hours in the morning and a couple hours in the evening. We have two 1,000 liter storage tanks. There is no problem with the tanks sitting at ground level if you use a pump.

Trust your wife. It should work - even without having a tower (but that will at least give you some flow during electric outages if you have a pump bypass). I have never seen 1 and 2 inch water pipes being used for homes here. Normally it is 4 or 6 hun (1/2" or 3/4"). At least it will not be your fault if anything goes wrong.

In most cases you can do outside wall runs for water lines to avoid cutting walls/floors. For some homes it would not work but for many it is not even seen as runs are in rear or side. Much easier to service if something goes wrong. When painted the pipe is almost invisible.

In my first post I said we should open two walls. That way I can mak three waterlines - one for each room - fed by a distributor from the big main water tube coming from the road. But she will not do it.

I will check the dimensions when I come home. But shouldn't there be a pressure tank after the pump to avoid the pump going on/off all the time. Crossy's diagram in my link over shows this.

Normally the pressure take is part of the pump on home units sold here - bottom part will be the tank with the pump mounted on top of it. If not then yes you should have a pressure tank that turns the pump on/off.
