I see the blue plastic tanks all over the place in my area . Are the blue plastic tanks the best ? I have noticed that the neighbour s tank (looks like a 2000 litre blue plastic tank) sits on a 30-40 cm concrete base/slab … what kind of base is required ?

I think 700ltr tank is sufficient with a 150 watt automatic water pump, unless you're in an area that experiences frequent water supply outages. Then you may want to consider a larger tank and having the number to a private water supplier would be handy also.

Our tank sits on 20cm base and combined with the water pressure in our area it supplies water to our first floor effectively.

have something similar to the diagram posted.. 1100 liter tank built on top of a storage building with a peaked sheet metal roof to keep the sun off the tank.. City water feeds directly to 1100 liter tank which has a floating ball valve to shut off the main when it is full.. The tank feeds to a Hitachi demand water pump which pressurizes the house water pipes and feeds the toilets sinks and showers. We too rarely have significant power outages other than just the other day when a lightning strike on the east side killed power for about 8 hours.. I finally went out and bought the fittings to bypass my demand pump and directly feed the house from the tank per KD's explanation... Oh, BTW, as near as we can figure our 1100 liter tank gives us about 5-7 days of water in the house...

Hmm, I must have thin blood or is it thick? My stainless 1100 liter tank gets sun from early morn to around 3PM, I take a shower at anywhere between 10 and noon, sometimes as late as 4 or 5, and still run the hot water. Maybe its because my pipes run under ground? But anyways the cold is cold.

Your tank is effectively solar heated. The earth acts as insulation (below 6 ft earth would act as a cooler). So, it makes perfect sense that your water runs hot. You didn't state it, but it runs really cold during cold season after it cools overnight, then warms up considerably by noon, right?

Shade the tank and the temperature will fall to ambient.

You lost me there, KHONDAHM. Guess what I was trying to say was that I still need to use the water heater, even during Hot weather, and that the tank gets direct sun most of the day.

The way some were talking, with the tank in the sun the water was too hot. With mine, if I need a cold shower, I just turn on the cold tap. But then again whats cold to me, others might think warm, like the wife, she just uses the cold except in December.

Oops! Perhaps I misunderstood the post.

Cheers!

The house is a 4 bedroom with upstairs, 3 bathroom with one of the bathrooms upstairs.

What size tank is recommended as well as the rating for a pump sufficient to run this lot?

Anyone know a local chap with a good reputation for installing such a system?

Many thanks,
