Hi,
I'm contemplating replacing an existing electric shower (Triton Zante III) with the exact same model as the existing one is broken. It all looks fairly straight forward apart from disconnecting and reconnecting the water-inlet. I'm wondering if I'll need any special tools for this and whether a sealant will be necessary. It also recommends flushing the system to remove any debris but as it's a straight-forward switch will this be necessary? Any advice would be greatly appreciated. Thanks.
