We've been using our TST for a year and a half. The only time we had a leak it was because we hadn't yet changed our rubber valve stems to metal which is recommended.
Do you have rubber or metal valve stems?? Rubber valve stems could cause slow leakage.
You might try to set the valve stem at the bottom position on the tire and pour some water over the whole sensor and valve stem to see if you get any bubbles. If you see them, try to determine whether it is the valve stem or at the o-ring of the sensor. If there are no bubbles, you may have a leak somewhere in the tire or rim.
I agree that a phone call to TST would also get you some answers as leaking is definitely not the norm. Hugs, Di

I concur with the other comments regarding the rubber washers. I do believe it is a problem. I bought new tires two years ago, and I have not had to add one pound of air since then in any of the tires.

That was until I installed the TST sensors. Now I have one tire that loses about 5 pounds every couple of days, and two tires that lose 5 pounds every couple of weeks. I haven't talked to the folks at TST about that yet, but I will. Maybe I can get them to send me some new washers.

Is it only the TST tire monitors that have the rubber washers and not the Pressure Pro monitors?

After buying the Hawkshead system right before christmas I was having trouble installing the sensors on the inner back wheels. The valve stem extenders would not allow the sensors to sense air pressure. But this past week took a trip to Key West and my brother in law also a hawkshead user helped me get things right. I can tell you that I am really happy with the system and feel so much better knowing that I can monitor my tires. My fear was getting a flat on the toad and dragging it till the tire and car was damaged. The system works perfect, with no problems reading my toad with out a booster. I have a 38 ft coach.

Thay all do. In order to sense the air pressure, they have to hold the tires schrader valve open. So they have to seal against the face of the valvestem and then keep the air in.
