"You can't beat McAlpine fittings. They are very well designed and constructed. They will fit all similar sized makes of plastic waste pipe. The fittings can be opened up and refitted easily for maintenance needs unlike cheaper glued fittings. This trap is ideal for use with a washing machine or dishwasher. McApline make various traps to suit various needs including multiple connections should more than one utility connection be required. Being a plumber I've used McAlpine since the 1970's and find they are by far the best. High recommended."
"I bought the floplast version of this which leaked at most joints and felt cheep. I replaced it with this quality well made item , well worth the £5.50 extra. The price reflects the quality difference, the old saying you get what you pay for applies here."
