Query: Are thre any safety concerns using a plug in lamp dimmer switch with other non lamp electronical appliances?
I have a cat founatin whose pump is too powerand it creates splashes which scares the cats. I was thinking of getting the dimmer switch to make it a trickle that wouldn't splash.
The wife bought it and while typing this, I know wonder what advantages the fountain has over a bowl.
yes if the dimmer is a chopper type thing which inevitably it is then it wont work with inductive loads which is exactly what a motor is. well, it will work but the dimmer will be under a much greater load and could melt and explode.
this is why things like dimmers and occupancy sensors have different ratings depending on the lamp technology, fl, cfl, halogen, led etc.
Those motors that come inside cat fountains are usually pretty small and low current and, if I recall, have a disconnect plug half way down the wire. With a little bit of calculation, you may be able to insert a resistor in to the disconnect plug to throttle the motor down a little by limiting the current to the motor.
Strike that. Even though that solution may still work, first things first. Remove the pump from the cat bowl and look for a small knob on it. Turn the knob all the way down and reinstall the pump. Problem solved.
>recycling old dirty shit water for your cats to drink.
build your own fountain out of a couple of tubberware containers, connect it to cold water supply and drain, use gate valve to reduce the flow, you only need a tiny amount. here there is a standing charge for water only, if you pay for your water by amount you can add a sprinkler valve and ir sensor to turn it off when no cats are around.
clean fresh water for your cats everyone is happy.
Dude...I luv tubberware shit...I went to a tubberware party once, and one of the chicks in the tubberware was just like polluted...no what i mean verne...anyways, long story short...I ass fucked her titties right there at the tubberware pardy with this like uge smack of peeps allarone an shitz...
disagree. dump out and refill water every week or so. fountain tricks cats into thinking water is fresh and aerates it so it does taste less flat/more fresh. hooking it up to new water will spike your water bill, and you have to worry about drainage.
A better solution would be to get out a drill and drill holes in the plastic column. more water outlets, lower water pressure, no splashes. drill too many/too big and the water will just dribble out though.
has a point, inductive loads pulse so they spike the stress on the dimmer switch. However given the size of the motor, you would probably be fine with a lamp dimmer. those motors are often like 0.1 amp. it may drop the lifespan of the motor 20% though, because of uneven power. But >>935237 is a better solution if you have a soldering iron.
The fountain aeration thing is the same reason why many dogs like to drink out of the toilet, and many cats like to lick faucets for fresh water. The air bubbles in water settle out.and make it taste flatter/stale.
