If you are talking about the cheap soaker hoses that every hardware or garden store sells, I can't imagine water so hard that it would plug them. If it does, just turn them on, and if you find an area that isn't dripping, just prick it with a sewing needle where you want more water. Their biggest enemy is UV rays, but under a layer of mulch (where they
should be), they should last at least until you say "OOPS!" one day while hoeing weeds.
