Inserting washing machine valves into middle of copper pipe?

[Pipps]

Should it be possible to add a couple of washing machine style tee valves in the middle of these copper pipes?

Forgive the basic question, but I am an inexperienced home owner. Thinking of giving it a try myself today.

Would this risk reducing our tap water flow from the pipes continuing above, or any other potential issue?

Not enough on the vertical but maybe on the horizontal depending on how much you have left of the pic

Thanks! Once installed, will we notice any loss of pressure to the taps above?

with the outlet / washing machine /dishwasher filling maybe but only when its filling dont think it will be much unless your water pressure is that bad

The type of cutting in devices you are proposing are really not very good. They restrict the flow just to do with the restrictions necesssary to be functional. However properly fitted they hopefully
1. will not leak 2.will supply water at a suitable pressure and volume
3. will not leak over time. Its a one hour job for a competant plumber
to set the system up properly...I would go that way ....centralheatking
