"removed my heater in no time. fitted the new one. In all it took me about five minutes excluding draining tank. you always get someone who expect something for nothing and then moan about it !!!!!!!!!!!!!!"
"Spanner fitted perfectly after a few burrs were lightly filed off. Much stronger than a pressed steel cranked spanner, it removed the old heater and replaced the new one on a foam insulated cylinder with no trouble at all.
"I would just like to add the other comment here. The spanner fit my old immersion element and the new one (from Screwfix) just fine. The old one was hard to get out, but the spanner did it without chewing the nut up or slipping. It it slips when putting in the new element, you're doing up too tight!"
"The spanner does not fit easily and snuggly on the immersion heater nut - you have to tap it on. Having said that it did the job and was very cheap compared to others like it, so I'm happy. If I were a professional plumber I might go for a better quality product."
"Spanner was too big for old heater. I had to bash flat sides of spanner with a hammer to stop it slipping. Spanner fit new heater ok but was still not a tight fit. Were these heaters made smaller years ago? The old one I was taking out had been there for about 30 years and was stuck solid. I heated area with a gas blow torch then gave the brass part of the old heater a couple of squirts of cold water. A sharp tap on the tommy bar of the spanner and hey presto!"
"Spanner was just too big and slipped round immersion heater nut. As these are all standard and this is a specialised tool solely for the purpose you would have thought the manufacturer would have got it right. I cannot recommend."
