New build, i'd ask for a refund, half the pipes new the other half old looking at it and must of spent a fortune on compression

I am glad the OP labeled that pump otherwise I would have never spotted it, Joking aside.

"I would really appreciate any help"

here we go then - admit that you were wrong when you though you could install your own plumbing, then employ a proper Plumber to come round to sort it out, what ever they recommend to correct it have done despite the cost.

Then put the sorry lot down to experience !!
