kinked

I’ve had new cold and hot water tubes fitted, however a plumber mixed them up. I called him back to rectify and he had them swapped. As they now cross over, he decided to bend the cold-water pipe over a joist causing a small kink. I asked him to replace that section but he refused. He said it...

Hi. Just had some repair a small leak I had on a bathroom tap - it's an awkward spot so got someone out to do it. Apparently, the washer was gone. They have fixed the leak but I have just managed to have a proper look, and it seems like they have kinked the braided hose. Should I be worried...

I just found this as I was doing the waste for my bath, it must have been like this for 10 or 20 years, but it doesn't look great to me Would this be something ok to leave as it is, or should it definitely be replaced with a straight coupler by a plumber?
