Tell Tale water flow on 2005 DF140

[Pleasureway97]

The tell tale on my DF 140 tends to always have a low pressure stream, sometimes down to a dribble, and has been this way since new. I occasionally insert a wire into the opening and the flow picks up to some degree. This has not changed, even after having a new impeller installed. My dealer/mechanic states that the 140 is known for a weak flow.

Would it be possible to slightly enlarge the tell tale hole in the rubber piece with a hand operated drill to increase the flow and also reduce the occasional blockages that occur? I presently use a piece of coat hanger wire to get the water flowing again.

get another dealer not known for week flow .but it does get cloged up .you can take the pisser out and clean it .could also so be a thermostat stuck open.

you can pull the tell tale end out and check if the amount of water coming out. And check if it is blocked. when you insert a wire the dirt is pushed back and can block the opening again.
