Hi , I recently replaced the UV bulb on my Blagdon All in One 3000 pump. During the change over I noticed the electrical connections were not in an ideal state. I continued to install , the water condition did improve but not to its original 'crystal condition'. Now its very much pea soup. I intend to replace the entire unit and was wanting to know if anyone know if the Affinity 5 W UV assembly is compatible with my Blagdon 3000 pump.
