Hi. Failed MOT last week due to windscreen washer spray problem. The pump seems to be ok, I have cleaned the nozzles and checked for blockages in the pipes. The washer liquid is coming ok from bottle to first washer hose and I think I have isolated the problem to a little black connector to which both windscreen hoses are attached. Are these easily sourced and is this a common problem area?

Sounds like a 3-way connector, easily available from e-bay or a decent car spares shop.
