Welflos M 交換用リザーバープラグ

The instructions about inserting from the inside were spot on—once I did that, the water flow came back strong and steady. My flosser finally works like it did on day one.

I was about to toss my flosser when the water stopped building pressure, but this plug was the fix. Snapped it in from the inside and the seal held perfectly on the first try.

The plastic feels sturdier than the original, and the fit is snug once you push it in from the inside of the tank. My water flow is steady again after a month of frustrating sputters, which is exactly what I needed.
