Tom –
Easy to install and set up. I’ve got it connected to a small indoor water feature now, and it keeps the level constant without any fuss. The kit has all the connectors you’re likely to need. It’s not the most elegant looking thing, but it’s functional and does the job reliably. Good value for money if you need automatic refilling.

Bought this for my Mars Hydro humidifier and it’s been a game-changer. No more getting up to refill it every night! The setup was straightforward – just followed the instructions and had it running in 10 minutes. The float valve works a treat. My only tip is to make sure your water bucket is a bit higher than the humidifier, as they suggest. Proper chuffed with this little kit.
