Resolved my Hydropool Serenity 5000 Circulation Pump Issue
Thursday, 14 January 2021  |  Nathan

My hot tub (Balboa topside) was throwing a Heater Dry Flow Error and after excellent advice from the Hot Tub DIY team determined that the issue was being caused by no circulation to the heater. Having tried various other tips online to release air locks (which didn't work) it was clear that the low speed capacitor needed to be replaced - not the entire pump. Accessing the capacitor was tricky due to the sealed cover being so close to the underside of the hot tub, but after some time I was able to gain access and then the swapover was very easy. My Hot tub is back up and running and the team here saved me having to call someone out which is almost impossible during lockdown. Perfect. Quality component with fast delivery. Great job.

Know your hot tub; Know your pump

Owning a hot tub is wonderful. The bliss of being able to switch it on and unleash the therapeutic power of the jets is something you can’t live without if you have experienced it. But there will come a time when something may go wrong. You may have had your hot tub for a few years. Either way, getting to know your pump, its specifications, capabilities and limitations is vital in enabling you to make the right choice when buying a new pump. It’ll save you money in the long run as well.

Hot Tub Floating Chemical Dispenser

Keeping your water sanitised is a really important part of maintaining your hot tub. One way you can do this is to use a floating chemical dispenser. Using a floating dispenser with either chlorine or bromine tablets keeps your water clean and healthy. It just floats on the surface of your water and you regularly put tablets in it which slowly dissolve over time.

Tablets have become more popular over the years, as the inflatable spa market as grown but many hot tub owners use them too. They are cheap and easy to use. A floating chemical dispenser is not the only way to sanitise your hot tub, you can also use an in-line chemical feeder or a skimmer basket but the floating dispenser is more popular because it’s so easy to use.
