For Kobo Kobo, Long span is a sure banker!! The gauges are all good depending on your pocket.

oduncojamaica:


If you are going for step tile - minimum of 0.5
Long span - 0.45 is good

Based on my experience in water tanks installation both in theory and practical.
If you have a building of 20-24ft it’s strongly advisable to do height of 30-38ft water tank.

If your building is btw 9-12ft (bungalow) it’s ok to do btw 15-18ft water tank height.

Here is it in theory and practical
If you need 1-2bar of water pressure which is just AVERAGELY ok for domestic building your tanks should be in height of 12-18ft in a bungalow this will give you 1-2bar which means a bucket of 20lts will filled up btw
2-3min
In practical plumber will run the supply pipe through ground which means the water tank still remain 12-18ft height to supply such pressure BUT if he try to run the water through roof it mean the height is just only 3-6ft which is VERY BAD bcs water heater will not run and shower also.

In case of a story building it’s the same theory and practical.

If your tank is 25-28ft and you run your water through roof same WATER SHORTAGE will happened bcs the height you have at upper floor is just ONLY 5-8ft ( the building height will be btw 20-22ft )
And if you run it through ground then go back up water shortage will still occurred in upper kitchen, shower etc ( it’s real ) means to filled up 20lts bucket it will take like 5-6min at 0.5 BAR mostly when your water reaches half tank … Any body can try this.

Most of my project I usually do 35-38ft ( duplex)
15-18ft bungalow.

sethtsadopp:


Thanks sir.
By the way, I know you're a very meticulous person so I wanted to know, has he done any cubicle work for you and recommended.

hamtabfawaz:



Unfortunately, I don't concur with you on this.

michlins:
the reason why public waters are elevated is because they're not serving just a duplex. It's public water and there are instances where some houses are taller than 25ft and high as 50ft. You will not notice any drop in pressure until the last drop of water off your tank.

Going by your analogy,in instances where you have 4 storeys building,that means you will have to do 90ft tank stand since you want to double the height.

The height of the water overhead water tank must be adequate to ensure a constant minimum pressure to all outlet. See the attached as a guide. This is best practice.

a four storey building is 45ft, what's the ideal height of the tank stand and how do you intend to practically achieve it

rotecch77:


You want me to go deeper on water supply System both in domestic and industrial system. Well it what I know but I will just explain it in simpler form

You see high rise building and sky scraper water supply system connection is a bit critical.
This is it l, most of these high building mostly have there water tank setup on ground floor and a well design transfer pump will be installed to do the job plus booster pump in each section of the building ( the explanation is much and the sep up is critical than what I can explain fully here.)
Again some also do have GIANT WATER TANK with about 12inch diameter pipe from the height of about 100ft with about 100bar pressure to supply any building around the municipal, this system doesn’t need any booster pump to get pressure in any building around bcs all building around will be tapping the water from the 12inch pipe with 1 or 2inches pipe to supply such into the building
Imaging the pressure you wi get from 12 inches pipe to 1inch pipe.
Here is the standard system


It’s a whole lot of work ooo

michlins:
Until lately, tanks are placed on the rooftop and the water pressure is adequate for the home it's meant for. What suddenly changed or are you discussing issues you know absolutely nothing about.

Gravity is same everywhere, you don't increase gravity by increasing height of the fall.

Once your tank is above your shower head, you already have enough pressure you need.

That being said,if you want to do 60ft for a bungalow, it's your money and I have zero control on how you choose to spend it. If anything, focus should be on the foundation of the tank stand.

michlins:
I'm not talking about commercial skyscraper. Just a four storey building with just about eight flats. What's the ideal height of the tank stand?

You folks have a way of making simple things very much complicated

See, to whom it may concern, once your tank stand is at same height with your parapet, you're good to go and you will not notice any significant loss of water pressure until last drop.

But if doing 40ft tank stand for your 23ft building will give you the satisfaction of maximum water pressure, do it. If your standard is public water system that services homes hundreds of kilometres away,aim for it. The sky is your limit

It's your money that you will spend and if you pay me, I will do exactly what you want.

visaclick:
stop arguing the obvious, rotecch77 is very correct. My dad's home due to him being on budget he installed the tank overhead the kitchen and the bathroom shower can't even run properly, the kitchen tap is even the slowest and now we are planning to get the steel tank sooner. A water tank has to be sufficiently higher than the last floor level to gather sufficient pressure for Optimum h20 supply.

FEGEITOK:


I have experienced this before.

Question though what if someone has several thanks at that level, say 2 or 3 all connected to the same flat?

Would it still have pressure issues?

Please House where can I get original ceiling PVC in Lagos here.

Also at Ibadan

ANy leads?

diordaves:


You MAY still have the same issue irrespective of the number of tanks.

The game changer is at the position of your water heater as this is the highest point (outlet) of use in homes.

From the water heater point (level), the base of your tank must be minimum 5 meters higher to have good constant water pressure.

Again, the game changer is how high is the base of your tank from your water heater. If this is not high enough, you are significantly at risk to suffer periodic pressure issues.

visaclick:
if the tanks are connected in series then no it wouldn't. But talking about each tank supplying separate part of the building at lower head room yes there will be loss in pressure. This phenomena is similar to the fanta drinking straw . When the mouth is empty there's sufficient suction to draw up fluid but as the fluid fills the mouth theres less suction.
pressure increases with height and surface area.

Amoula PVC seems to be your sure bet. They have been around. They have office in Lagos.

P = pgh
Gravity and height are involved in determining pressure

FEGEITOK:


You are right.

Sadly in this case our resident metal fabricator got it wrong.

nice one bro congratulations. I knew this year will be a better year when I got alert on first morning of January

Rany4all:
If you drop an egg-sized stone on to your head from a height just an inch above your head, you'll hardly get hurt, but just imagine same stone falling from the top of a four storey building on to your head on the ground floor ....My brother, height does matter a lot, no need to argue this one abeg.
