Best Way To Plumb in Body Jets

[r.rain]

Hello All

Having just tested my new thermostatic shower out the body jets dont appear to be very good in the flow department. Im thinking its the way I've plumbed them in as the last one in the pipe run has particularly bad flow, the first is acceptable. I have just daisy chained them T'ing off a pipe run (15mm) which I was told should be OK!

What is the best way to plumb these in to see that all jets get equal flow or there abouts. I have a thermostatic mixer shower which is powered by a 3 bar monsoon pump.

TIA Cheers Richard

It sounds to me like a flow problem, I've 8 (2 x 4) jets running off

8mm piping with no problems with a 3 bar pump. Is the thermostatic shower valve/ diverter valve in front causing a pressure drop?

In what way do you mean, do I notice a significant drop in pressure when the diverter is turned to body jets? No I dont appear to. Do you suspect something wrong with the diverter??

I just went to the time and trouble to redo all my connections to the body jets but instead of using flexible connectors which looked quite small bore I piped up to it, this didn't make much difference though and water continues to piddle out of the last jet in the loop. I also swapped body jets over just to eliminate that.

Does anyone have any other ideas?

You should probably make an appointment with a urologist...

Nah he wont know the answer :)

For equal flow you should create a symmetric tree manifold.

From the Body jet supply (diverter) tee into two (left/Right or top/bottom for example) then tee each of these into two (four outlets at this point) then tee them again for the eight jets. If you use the center of the tees for the inlets and the ends for the outlets this will give equal restriction in the tees. The perfectionist will also ensure that the pipe segments at each level are equal.

In my shower I created two identical H shaped manifolds with a jet at each corner and supplied them from the center of each H crossbar. Being somewhat demented, I supplied each group of four from a separate mixer valve with a third mixer valve for the main shower head. With 5 bar mains pressure the flow is quite invigorating.

Thanks Jim, this is what I have done now but I'm still not getting good enough flow with a 3 bar pump. I have started another thread regarding this.

Cheers
