Customer Reviews for Black Easy Fit Strap Boss SP319
"I was a bit suspicious of this at first, having only ever used ones with a galvanised screw and nut previously, but I should not have worried. FloPlast stuff is good, and this is no exception. Feels well made, and the clip works well.
Cut the right size hole in the stack, rough-up the bits you're going to glue (around the hole in the stack and around the hole in the boss), brush solvent glue on both surfaces, and bring them together. The clip has one-way serrations in it, so you pinch it together using water pump pliers or similar, and it stays pinched together. Easy to do even if the clip in in some awkward corner. And presumably when those metal screws on the more common type start to rust, this one will still be looking good."
"Basically great, just a point though in case there are any other seriously amateur plumbers out there: if you're connecting a 40mm (or 32 or 50mm) pipe to a soil stack using this, you need a FloPlast adaptor as well, otherwise the thing will leak. Mine worked OK for a few months without the adaptor but then started leaking whenever water went into the soil stack on the top floor. It's not really clear from the description that you need an adaptor, although the product codes for the adaptors are mentioned. Probably this is something that every plumber knows, but I didn't, so thought this might save somebody some time!"
