Causes of Low & Lost Toilet Pressure, Flushes | A.J. Perri NJ Plumbing Skip to content

My toilet has lost pressure and barely flushes. What causes this?

If you have one of the first low-pressure toilets that came on the market, the best thing to do is replace it. If your pressure loss just happened, the most common cause is a clog somewhere in the drain line. Plunging may solve the problem, but you may want to have the line snaked.
