Yaris 1.3 windscreen washer problem

[Carryduff]

The front window washers on my 2010 Yaris 1.3  stopped working recently although the actual motor could still be heard running. i took it to my local guy who after pulling off all the plastic trim (including the two wiper arm) discovered that the problem was the small plastic one way valve in the hose line. The quick solution was to drill a small hole through the centre of the valve and everything worked perfectly again. I would like to get a proper replacement as soon as possible but want to avoid main dealers/big prices. possibly online ? any suggestions would be greatly appreciated.
