[hitchup]

Is it dribbling because of low water pressure or mineral build-up in the sprayer?

We're still on our original one after 3 yrs. But around the holes, it will get crusty from minerals. I flake them off with my fingernails or an old toothbrush. But have heard white vinegar and a brush will dissolve minerals. (1 part water, 1 part vinegar)

Have you gone to Home Depot or Lowe's to look at their generic sprayer heads? For the price Dometic wanted for one, you can buy 3 or more.
