Pool plumbing - Pleaseeeee help!!!! Please!

[shlomikalfa]

Hi,

My pool is ~3.7m * 4.5m * 1m
concrete + vinyl cover
skimmer + main drains

I want to add a "spa" area with some jets.

so, my question list:
1. Which pipe size should I use from the filter to the pool inlets?
2. Which pipe size should I use from the pool to the pump?
3. Which jets should I place and what are their requirements (pump-wise - how much m3\h should it be?!)
-- If you can provide a purchase link it will be great!

Hi,

I'm making my own pool DIY style and would really really love it if some pro could have a look at the plan and spot my mistakes before I ruin everything

So far I've got my hole ready, now I need to place the plumbing and go on with the whole cement pouring etc...

My plumbing plan is:
Plumbing
My yard hole:
Hole

2 systems, 1 for jets and 2nd for the pool circulation.
I think I've included all details on the plan itself.

Main questions:
1. Will the jets work on this pump with these pipes?
2. How do you plumb the jets/spa area? Do you make a 75\90mm pipe all the way there and then just continue for the entire area with 1.5"? Or maybe you just downscale/upscale for each jet connected?
3. Will the pumps create too much suction and drainers will become dangerous?

I have plenty more but I don't want to drop the whole lot on you at once

Thanks for any reply!!!!

Just to let you know I am thinking about your situation, I am very busy at the moment so please be patient. Are the 4 floor drains the supply for the spa system of have I miss understood?

What filtration are you using? What is the estimated total volume of the pool?
Sorry travelling by train so maybe asking for a detail you have already included but the picture is small on my phone.
