    Hi guys - what is the difference between the two waste types. As I understand both enable water to drain effectively and both can be used with shower trays but how do we know which one to buy? Also from the sizes they both come in 90mm. Are Mcalpine wastes the most effective or can I just go with the recommended waste in the online website?

    Thanks Scott! Should I go for a high flow or fast flow waste?

    TBH they both do the same I would think but I would go with high flow
