There are so many shops that sell plumbing material and they also have plumbers available. The area I live in has about six of them. Most plumbers they have are part timers and are available after 5 PM. However, you may contact one Yousuf at 55282375. He is a good plumber who also has his own transport. He speaks Hindi or Malayali. He may help you out. Tell him of your problem over the phone and he will come over to your villa with the fittings. That would save him an extra trip.
