"To add to overall support of the downpipe fit the lowest bracket below the collar of the shoe not above on the pipe. This will stop the whole pipe sliding down. Why on earth are people suggesting solvent adhesive. - No - use enough brackets and do the job properly."
"Good value, good quality drain fitting. Perfect for tidying up a cracked end piece and routing water flow away from the edge and into the centre of the drain. 10-year guarantee is reassuring but really should last longer."
