I think you are correct,
When I was monitoring our usage before setting up our storage, the 3 of us used a total of less than 1000 liters a week, and then had 40 [150 liters] gals a day max with washing machine, showers and our total and so with 6 months with no rain that 30,000 liters would carry us thru and it has except for the drought year and we were never full from rain so I had to buy 8000 gals.

Like your Av. I was civilian.

This is a much better solution than repairing the mains, obviously, even if it means their customers don't get any water.

Well it could be that the water company is betting on people installing their own pumps - lowering the delivery point pressure is a convenient way (for them) to maintain pipeline capacity at a lower mains operating pressure.

Could there be another aspekt to this waterpump permission?
What if some Ding-Dong hooks up the waterpump the wrong way?
Pumping dirty water into the fresh water system. Don't you need some kind of cut off when different water meets in a pipeline (water from the tank/water from the city).

Where do you suppose he is going to pump said dirty water from?
If a Thai had water to pump he would pump it to his house line or taps, and he well might be getting it from a jetted hole 4 meters deep and a 2 " pipe just 1 meter from his cess pitt, but even a Thai will not drink tap water here, they do recover rain water into the Thai water jars when it rains and like it better than bottled water to drink, bird shit, drowned rotten lizards, and all.
At our house we even use bottled water for tooth water and not the tank water, and in this Moo Ban there is so much chlorine in the water it taste liked drinking clorox or Purex right out of the jug.

With your set-up, the size of the tank is imaterial BB

if the water supply is cut off and the pump is working to fill the tank, it will damage the pump unless you hear it running forever.....

Really to me it does not sound like a Lot of common sense is used in some situations, But of coarse a lot of folks have never been exposed to these things so pobly if you want to talk about English Lit. then I would sound as if I had no common sense at all.

When in fact I have been licensed by the USCG in both deck and engine as a Master/mate or as a chief engr/assistant, both Oil & Mineral and passenger carrying Vessels of either motor or steam and all blue water ships in one job or the other..

Just never had much school housing and paid little attention when I did take time to go.

Mmm. That's true. But if the tank isn't full, that means we're at home using water. If the pump goes for more than about 30 minutes after we finish, we should be able to work out there's something wrong.

I know, for example, that when I shower in the morning, the pump finishes its business before I have time to get dressed and leave the house.

But I take your point. I'm thinking of the current set up as a temporary solution to a problem that needs a better long term answer.

you can fit a flotation device in your tank that will cut off the pump power if the water falls below a certain level (near the bottom), that will protect the pump

I know BG, in Shakespeares "Love labours lost", the king Ferdinand is famous for saying "Jack of all trades, master of none"

or was that "Little Dorrit"?

Actually, in 1612, the phrase appeared in 'Essays and Characters of a Prison' by Geffray Mynshul

We already have a flotation device in the tank, which is what switches the pump on. How would a similar device also switch it off? I'm interested, but I'd like to know how.

I don't see how it can be easily done, you'll get a problem when the tank is empty.
If you switch off the pump at that point, what criteria are you gonna use for restarting it?

true, we used to have a bypass system that let the tank fill direct from the mains when that happened

at least the pump never burnt out

It is entirely stupid to put a pump where someone else controls the water into the pump and the flow is not at least capable of the full pipe size of the intake, liquid should never be throttled at the intake but adjusted at the discharge side.

If you have time in operation or horsepower, go and set for and recieve your USCG Masters or Chief Engineers licenses, of which I have done both at different times. and then tell me about "lack of all trades and Master of None"

What water he has in his tank at any time is or no relevance to his pump, if the tank is 1/2 full and there is power to his pump and no water is available it will still burn his pump up just the same as if it were empty/full,,,no water into pump=burnout.
The only safe way it to have a mains filled reserve tank before the pump and his pressure house system after the pump.
End of story, I am outta here,, Good Christ.,.

OK

that is the best way and is legal, as was already said

the other methods were suggested to help the system he already has

What is the cost of a second reserve tank inserted before the new pump, and how does this compare with the cost of possibly having to buy a new pump (1,500 B) should the original burn out?

That all depends on what tank you buy and how much you spend for a new pump, but if it burns up the pump you have thrown that money away.
So should have been done right in the first place and it always saves both time and money to do it that way.
I needed it done here when I moved in so I went to my friend who owns Home Mart and told him I wanted a reserve tank and a good pump and to have someone pick it up and come and install it and hook it up.
I got a good quality 700 liter tank that is UV resistant and was made for this use with a built in float valve and a good pump that will last and it was about 10K baht.
all depends on what you want to spend and the quality you want. I would rather spend more at first and have something that works and is trouble free than a cheap pain in the ass.

I just took this just now, and it will work as long as I live here and I can take it with me when I move if I want and just hook the pipes back as they were,
As you can see, this is the use it was built for.

I would take a pic of mine too, but can't be bothered

so benB, all you have to do is move the pump to after your reserve tank

the tank should fill when the pressure is higher (overnight) and the pump can then supply the house...except it is not a demand pump

but you already have one of those, I think, so the new pump was a bit of a waste of money. Mind you, at b1500 it is a cheapo anyway and would only last a year

oh well

If I can be bothered to take time to post info then I can take time to flik a pik out of my living room side window.
You surely must have heard "A picture is worth a thousand words"? well there seems to be at least that many on this thread and none seem to be understood.
