Mmm see being an engineer, its ineresting to see how people deal with equipment failure. i would temporary replace it with a standard "T" piece but i would still have to know why it failed, hence my reference to cleaning it. If, having done that to no avail, i would try pressured air as was suggested earlier. If i still couldn't get it to function properly, i would carefully take it apart, not with an aim to repairing it , although if it could be repaired all the better, but to see how it was made and why it failed. I couldn't bring myself to just through it away without knowing what went wrong with it and predicting its life expectancy due to build quality etc and if i was going to replace it. What could i expect from it. Hey but thats me David
