A slow leak in a swimming pool can be very difficult to find. The only option that worked on this pool was to go over every likely leak point and seal it. It worked on this pool. See if this helps of you have a leak or suspect a slow leak.
Here is clear aquarium quality silicon seal on

Amazon UK: amzn.to/2okIgiT
Using the above sealer did a good job on my pool and it’s still good a year and a half later on. Or you could try this specific pool sealer recommended by a reader, from Amazon uk: amzn.to/2wmbdRO

![How to Fit a LOW COOLANT WATER LEVEL Warning Alarm
So we all know how important it is not to run out of engine coolant water (hopefully!). Also its not unusual for some engines to use a little bit of water. Modern cars all have a water level warning system, but not a lot of older cars.
Here we fit a warning buzzer to an old LANDROVER Freelander 1, but a similar approach could be used with any car with the same parts.
Due to the water sloshing around in the tank, it is easy for the float switch that is used to give a false alarm if just wired direct to a buzzer.
So three different opproaches are presented for stopping annoying false alarms. The final solution I used on this Freelander was the last little circuit shown at time. 22:25. This circuit, while still being quite simple, filters out false alarms, but it also allows for continuous monitoring of the water level and will set off the warning beeper if the water level falls at any time while driving. The water has to be constantly low for more than 9 seconds.
For other cars with a squarer shaped coolant tank, which allows for a more horizontal position of the float switch, it may be the case that false alarms are never or rarely triggered by water sloshing around. If thats the case then you could connect the float switch straight to a warning beeper / buzzer or a light or even a speaking little microcomputer like the BBC microbit as shown in the video.
I have now changed the code in the BBC microbit shown in the video so that false alarms are filtered out by the software. If theres sufficient interest in this Ill provide more details later. It really is very easy to program those BBC microbit boards so dont think you cant do it.
I looked at fitting the same sensor on my mg zs, but the water level wasnt deep enough and the tank seam was in the way, so I couldnt use this sensor. When I come up with another solution Ill post that video as well.
Now here are some buying links:

![Remove Condensation From Double Glazing – NO COST Fix!
A ZERO COST, cheat way to get rid of fog / condensation in double glazed windows. This is how I quickly fixed my double glazing. It would have a very slight thermal insulation reduction effect but I think that is very minor compared to, for instance, opening a window vent. #condensation #upvc_windows #doubleglazing #upvcwindow #upvc

![How to Fit a Coolant Level Alarm - MG ZS, Rover 45 etc
How to fit a coolant level alarm to a car with a small shallow expansion tank like in this MG ZS. Same as the Rover 45 and probably lots of other cars. It would be easier to find a replacement later model tank that has the coolant level sensor built in, but as they are a bit expensive and not that common, I have gone down the route of fitting a level sensor to the existing tank.
It is tricky finding the right size sensor. Here is a link for the one I used:
From amazon UK: http://amzn.to/2sTSM31
Or on amazon USA: http://amzn.to/2tPKLAM
As you will see in the video I cut it down by 16mm so that it didnt touch the bonnet(hood). That would be slightly easier doing it before fitting it to the tank. It was quite easy with a small disk cutter. Cut 2 slots down the sides and one around the shaft 16mm from the top and then split it apart with a screwdriver and they break away.
In this example we use an led to indicate low water. Plenty on Amazon again:
Amazon UK: http://amzn.to/2tTuwCr
Amazon USA: http://amzn.to/2tZ1DFN
Also see my other video on fitting a water level alarm to a LANDROVER Freelander1: https://youtu.be/IQXcK0nf_MU
We use the same circuit introduced in that video for this project. Except we modify it to give a longer filtering time by increasing the capacitor to 10,000uF. That can be a 10v sort if the LED indicator is used. It would have to be 16v or more if a beeper is used. The circuit shown filters out signals from the sensor due to the water sloshing around the tank. It does a similar job to what the ECU does on the later model cars that include the water sensor as standard. i.e. The alarm wont come on until the sensor is giving a consistently low indication for 30 seconds or more.
Here a buying link for the 10,000uF capacitor from:
Amazon UK: http://amzn.to/2sOizyB
Amazon USA: http://amzn.to/2uRrNqn
For the buying links for the other components see the description in the above mentioned video of mine about the freelander1 alarm.
For the rubber washers mentioned heres buying links:
Amazon uk: http://amzn.to/2tTBpUb
Amazon usa: http://amzn.to/2tPt9VK
Stainless steel M10 washers:
Amazon UK: http://amzn.to/2sU56QL
Amazon usa: http://amzn.to/2sNsoN4
Now maybe I was unlucky but that sensor of mine had a small pin hole leak. I fixed it with 2k paint, which sets like a resin. Use gloves with that stuff and dont breath the fumes and read about safety precautions. The detail of the fix is shown at the end of the video in an appendix.
