Humidifier water valve


Seeing how we dont have many humidifiers in Las vegas, I'm curious what the failure rate is on the water valve for flow through humidifiers.

The Aprilaire 600 humidifier I installed in the neighbors house, has a stuck on water valve. She called me yesterday and said she heard the water running and when I got there, I had to shut the water supply off to turn it off.

I just installed the thing a few months ago, I hope the replacement valve lasts longer!
Even worse, because the blower wasnt running, the humidifier was sweating inside the cabinet and leaking all over her laundry room floor.

I hate humidifiers for this very reason. Frankly, unless you really, really need a whole house humidifier, there is no reason to own one. You can get room humidifiers and ultimately they are better because they can put the humidity where you want it.

We really need humidity in Vegas in the winter.

I and the neighbor had portable units and got tired of messing with them and most models now only have a wicking type pad and after a couple weeks the pad was shot, wouldnt wick anymore.

I have no problem with whole house units but would like to see a water valve last more than a few months.

as BT said, it depends on the water quality.... you may want to use an inline filter.

the Aprilaire 600 doesnt use a wicking pad, that is the Aprilaire 400.

not to insult you with this question but did you install the solenoid valve with the flow going the proper direction? solenoids need the flow going a specific direction (the direction of the arrow on the side), otherwise the flow will never shut off.

I said the portable units we were using had wicking pads, not the whole house units.

The aprilaire unit is assembled already, I hooked the water line to the only end that was available. I'll double check and make sure they didnt reverse it at the factory but like I said, it worked fine for several months.

It's plumbed with hot water, never seen an inline filter for hot water. If you know of one, let me know and I'll have her buy it.

There are a number of hot water filters on the market. You simply have to adapt from the 3/4" inlet/outlet to 1/4".

I've seen and used many inline 1/4 inch filters for hot water

Honestly, I don't remember the brand I wanna say Honeywell but I was at a supply house and I asked for an inline filter for a steam humidifier an employee was installing and they gave me one with 1/4 in push fittings on it

A steam humidifier uses cold water and should never be installed to hot water.
