Harris Plumbing, family owned and operated since 1974, will be available for plumbing emergencies 24/7 over the August 1st weekend. . From our family to yours: Have a safe, fabulous long weekend Newmarket!! . Tip: on a septic? Tell guests not to flush AnyThing but TP down the toilet. Items that say "flushable" are NOT and will cause you grief & cost you $. They bung up municipal systems too.
