Question: what is the verticle travel - on to off - of the switch?
Document: I got my float switch in a timely manor. It was easy to install and worked well. All the parts were there for install.
its a float switch water goes up float goes up pump comes on. what more could you ask for. its a must for any sump pump.
I bought this switch because the space that our sump pump is in is deep and narrow, making it ideal for a vertical float. It has proven reliable. It was very easy to install and if done correctly, the rig should be plenty stable.
If you have a sump pump don't wast your money on those other switches that bob up and down turning the pump on and off. The ball inside gets corroded after a short time and stops working. This switch is a simple on and off type and gets a lot of use here in Alaska and has been working perfectly.
(If you can start your pump by giving the exit pipe a shake, it's the float switch. The pump works intermittently as the switch fails to make contact on some occasions). I found complaints online for all levels of sump pumps so it becomes a question of who can you trust?Delivery was quick as the point of origin was NYC and I'm in NJ.
This switch from Superior pump is actually a SJE Verticalmaster switch under a different brand name. These are good quality switches that typically last well over 3 years. However, the switch arrives disassembled in the box and there are no instructions for putting it together (there are instructions for how to put it in the sump pit). This is important because you have to follow a certain assembly order or else run into problems.
Then you slide the plastic rod into the switch making sure the indentation on the rod is aligned with the small pin hole next to the opening of the switch. Then you slide the small plastic pin into the hole and snap it in. Finally you put the float on the rod and slide the rubber stopper on below it.I made the mistake of attaching the plastic rod with the plastic pin before putting the metal support on.
This works perfectly for my situation. I have a sump pump that came with a tethered float switch. The switch would constantly get hung up on the side of the basin/pump. Set up is extremely easy with the included instructions. The rubber stopper allows for a varied range of operating levels.The pump runs from when the float reaches the top of the plastic rod until the float returns to its original position.
I thought $30 for just the float switch was a bit high but it seems that the internet has eliminated competitive pricing. Still, it was less than the cost of a new pump, plus the last two pumps I purchased did not fail - just the float switch. It was less expensive than purchasing at Home Depot. Then again maybe you shouldn't be trusting your basement to the least expensive part.I'm hoping this is of higher quality than the original.
WORKED GREAT AND IT KEEPS MY HOUSE DRY
