## Description

Spare Oil Watchman/niveau Battery/powertube : desertcart.co.uk: Fashion

Review: Works Perfectly, but Keep the Old Tube - It does the job it's meant to do, but I'd advise keeping the old powertube because it's merely a copper tube containing AAA batteries. The copper cap can be removed from the old tube, in the way described by several other reviewers, and the old one can then be kept as a spare.
Review: Did not work on my tank - Could be the sensor or the battery no way of knowing. However it was what I ordered

## Questions & Answers

**Q: If the plug in receiver is flashing "Bat Low" is this part suitable to solve the problem or is there battery I can buy to go in the power tube?**

**Q: replaced watchman plus battery tube but still flashing low battery?**
A: sorry, I cant be of much help - I have had to unscrew and rescrew the tube once or twice - but that's it

**Q: Do you need atube for a watchman sonic**
A: No. Its a button battery inside the unit.

**Q: where is the power tube**
A: It's the copper tube sticking up from the top of the tank.

### ⭐⭐⭐⭐⭐ Works Perfectly, but Keep the Old Tube
*by I***D on 14 August 2018*

It does the job it's meant to do, but I'd advise keeping the old powertube because it's merely a copper tube containing AAA batteries. The copper cap can be removed from the old tube, in the way described by several other reviewers, and the old one can then be kept as a spare.

### ⭐⭐⭐⭐ Did not work on my tank
*by D***L on 16 March 2022*

Could be the sensor or the battery no way of knowing. However it was what I ordered

### ⭐ The supplier has got impractical people like myself by the proverbials
*by G***Y on 8 October 2016*

This piece of kit is a rip off as described by many others. It is a simple piece of copper tube with four batteries sealed in side The cost of this to the supplier can only be a couple of pounds but yet it costs approx. £35 to get it delivered. The supplier has got impractical people like myself by the proverbials !! There is a procedure whereby you can unseal the tube and replace the batteries yourself for just the cost of the batteries using the existing tube but you need to be experienced with the appropriate tools . Not easy for people like myself. If the original tube could be supplied with a "screw off" cap this would be the ideal solution but sadly would reduce the profits for Sensor Systems!.
