Hi all,
I am going to install a pool within then next 6 weeks and have the design
and costs sorted. It will be 45 foot x 28 foot and is poured reinforced
concrete. I have poured this sort of tank before for agricultural
applications (Slurry catchment !) and it is really not a difficult job.
What is new to me is the plumbing layout. I need to know where water is
taken from to be heated and where it is delivered back into the pool. it
wouldn't be appropriate to heat water with a 500,000 BTU oil fired burner
and deliver it via a 3 inch pipe !!.
Is the water mixed with colder water drawn from another area of the pool
before being introduced to the pool ?
A website with a forum would be helpful or just somewhere where info could
be found. Any help would be appreciated. I will be putting up a website to
show the project from start to completion.

Even without heating, mine has a complex set of pipes, valves and pumps.

The main part is an 8-way valve, that normally is set to pump water through
the filter. That water is drawn in through two overflow intakes, which set
the minimum water level, provide a coarse basket filter and give me
somewhere to drop in the chlorine blocks. It is passed through the filter
and pumped back out through two submerged nozzles at the opposite end. By
turning the valve, I can backflush the filter, dumping the water used to
waste (the field next door), rinse the filter after backflushing (again
dumping the water), empty the pool through the bottom drain and do several
other things I've not got around to working out the value of.

Another set of three on/off valves allow me to run a different pump, which
sucks water in through a submerged nozzle on the side. That is where you
connect the accessories - a vacuum cleaner for the bottom and the surface
cleaning robot. You will also need somewhere to store the long brush, the
net for fishing out dead mice and the leaf skimmer.

Personally, I would never buy anywhere with a swimming pool again. They need
constant attention and are far too much hard work. The most I would consider
would be a sitting tub, which can be emptied when it is not needed.
