I've been looking at the instructions for deep cleaning a sand filter. I have been watching videos on youtube but I cannot work out how to open our filter safely.
Here is a pic of the filter and pump set up: https://www.facebook.com/KeelieReade...5875421&type=3.
Everything I am reading talks about depressurising the filter and draining it before opening and I have no idea how to do this.
I cannot find a plug on the bottom of the filter nor do the instructions indicate that one exists.
The filter instructions say to open all air bleeds, close isolated valves where fitted and remove pipes.
Where are the air bleeds and valves? Is that a valve at the front of the pump? It also looks like a little plug at the front of the pump - is that what I use?
Can anyone help?
