Late in 2006, I had a new furnace, A/C, Honeywell whole house
humidifier, plus electronic air cleaner installed in my home. Once the
cold weather hit in the fall, the heater did not come on. The solenoid
to the humidifier was replaced to fix the problem. Fast foward to Dec
06, the humidifier is not working. The solenoid is replaced again.
All is well until I turn on the heat for the first time last October.
The humidifier is not working. I call out the company that installed
the system. This time the saddle valve that feeds the humidifier from
the hot water side of my water heater is clogged. The tech opens and
closes the valve a few times and water starts flowing. I drained the
sediment out of the bottom of my water heater and changed the
humidifier filter a short time later.

The humidifier stopped again a little over a week ago. This time I
made sure that water was going to the humidifier. There is hot water
in the bottom of the rubber tube that goes between the solenoid and the
filter housing. The water is not making its way to the filter housing.
I blew air and water through the tube. I cleaned out the connection on
top of the housing. It still would not work. I made an appointment
for the tech to come out again. The guy who sold me my system called
me yesterday wanting to troubleshoot over the phone. We did pretty
much the same thing as did before I called and water started flowing
through the filter again. At that point, I thanked the guy and
cancelled the appointment.

A few hours after it was fixed, the water stopped flowing through the
filter again. There is hot water in the bottom of the rubber tube
where it attaches to the solenoid, but it is not making its way up to
the filter. The guy told me that if this happens again, to call a
plumber and have him install a T-joint in the water supply since he is
sure that it's sediment in the saddle valve that is causing the problem.

Correct me if I am wrong, but if the saddle valve was clogged, would
there not be any water making its way to the humidifier? The problem
is that the water is not being pushed up to the filter. Is that the
solenoid's function.

Any ideas? I don't want to waste money having a T-joint installed if
that is not the problem.

BTW, the humidifier is a Honeywell 265A.

Thanks!
