Water Softener (Park Hill CR0)

This offer is for an electronic water softener. I'm not sure if it needs servicing because just before I replaced it with a new one, it was stuck in the regeneration cycle (stage 2) but then when unplumbing it I found a small blockage in the brine drain which may have been causing this. Even if the blockage was not causing the issue, it may very well be a simple repair or an unblocking for someone who knows what they are doing. Although the softener is now far from new (2004) it was thoroughly serviced only a few years ago and was working fine until a fortnight ago.
