Does the unit have any overflow safety provisions?

The water is fed into the chamber by power being applied to a solenoid valve. The water flows over the media where the warm air passes through it adding humidity to the return air. Any water that does not evaporate into the air stream flows to the bottom of the chamber and is drained out of the unit via 1/2" hose. The only way that there could be an overflow situation is if the 1/2" line got blocked. Proper installation and regular basic maintenance should avoid that.

there is no reservoir, that's the beauty of this kind of humidifier. no stagnant water sitting in a tray. the water enters from the top, cascades through the filter and discharges via a flexible plastic hose at the bottom. you need to have a floor in reasonable proximity to the unit. at least in the same room.

This is a drip type unit so there is no water pan as there would be in a drum type unit. I previously had a drum type unit and it did overflow due to sticking of the float switch mechanism. That is why I changed to a drip type unit. There is no mechanism in the Aprilaire 500 to detect water not draining properly, but I have used a drip type unit for several years and never had a water leak issue. Note that you must either run the drain tube to a sink or floor drain, or alternately to a condensate pump. Since my furnace is a high efficiency type, I need a pump for that condensate as well as the condensation when running the AC. I just added the drain tubing from the humidifier to the same pump.

I installed the unit with a 3/4 " drain pipe directly to floor drain sump - so no overflow problems - the aprilaire 500 solenoid will only open when the unit detects that humidty needs to be increased - water will only run when the solenoid is open - there is no continuous water running at all like other units that do not use a solenoid water valve

I have slightly overfilled it with no problems. It's fairly easy to see the fill line on the reservoir.

yes, water flow is adjustable, also hot water safety adjustments if needed.everything is fine

I installed a PVC system for my unit and built it in such a way the the air must travel uphill for a ways thus making it more difficult for the water to get to the unit. I have had no problems with water in the unit. Hope this helps.

The "S' designates that the unit includes the overflow safety switch. The "T' indicated that the unit is supplied with tubing to connect it to other equipment.

continued from previous comment.... if your overflow fitting was ever plugged for some odd reason...one 1/4" drill hole anywhere in the lid would also prevent any sort of air locking.

Certainly, the sink has the overflow. It is a necessary to meet many city code.

Yes there is an overflow. It is the silver bezel seen in the picture. It probably gets about 2 inches deep before the overflow starts draining. This is an excellent sink I love mine.

Yes. I have had no problem even when it ran heavily along CA north coast one time. I have experienced no leakage so far.

It does come with over flow but it does have the "pipes" from the faucet up; but no other "pipes". Hope this helps!

The unit has flow control to limit GPM (gallons per minute) flow. Depending on whether your previous unit had flow control it may reduce how much water is flowing compared to previous unit. Many municipalities have a GPM requirement now. Whether this piece can be removed from unit is unclear.

Sounds like that would work, but we don't have an overflow issue. Maybe yours isn't installed properly.

This is a complete unit and does not need any external flow restrictor, universal fit

It does allow for the overflow to work. It has a plastic piece that has prongs that allow it to stay a few mm from the hole.

No adjustment on the unit, but water flow can be adjusted with the wall stop (shut off valve). But I don't know why you would want to reduce the flow?

It does have an overflow, no idea of the brand. As noted below , there is no lever to engage the closure, the one time I tried to push it down and then reopen I hard a very hard time releasing the closure.

The overflow problem I had was with pot lid flowing in faster than can drop into pot. So I made drain hole slightly larger. Have not had issues since. Drains into pot fine w/o a mess
