Over the Past several years in business our company has found some
surprising objects clogging toilets. Back in the day when toilets
flushed over three gallons of water at a time, most objects would sneak
by. Now a days being that toilet only flush around 1.5 gallons of water
most foreign items get caught up in the trap of the toilet. The only
item supposed to be flushed down the toilet is two-ply toiler paper.
Heavy toilet paper like three plus ply clogs the toilet up as well.
Some interesting items we have pulled out from toilet include: Credit
cards, wallets, tooth brushes, Toilet paper holder, jewelry, glasses,
denchers, kids toys, small travel shampoo and soap bottles, golf balls,
tennis balls, marbles, remotes, batteries, cell phones, blue tooth ear
pieces, silverware and the list goes on. When encountering a clogged
toilet don’t make the problem worse by handling it yourself. By forcing
the object down into the stack line it will just make the problem worse and cost more money out of your pocket. Call the professionals and handle the problem before is
worsens.
