Having pitched my Durango travel trailer on my permanent pitch here in Benidorm and just got everything plumbed in, I noticed there was little or no black waste coming out after a week. Thats it, bloody baby wipes. Two days of removing the the slide valve and rodding with all sorts of home made wire hooks later and all is now well. I do not believe some peoples mentality, two carrier bags full of baby wipes, cotton buds and even a plastic water bottle top in the black tank. Did they think it was a waste disposal system. Now I know why they sold it so cheap. Not one of my most pleasant jobs whilst overwintering in Spain. Ah well, back on the road in a few weeks with the fiver. Have the footpaths warmed up any back in the frozen north.
