Exactly what I ordered. Delivered very fast. Thank you. Review by Les (Posted on 29/01/2020)
Excellent money saver
I can’t speak highly enough of the service received. Knowing very little about plumbing, I was delighted to accept advice from Sparespro regarding identification of the required part. Quoted £90 for the job by a plumber, I’m more than happy to have spent £18 and ten minutes replacing it. Review by whatachef (Posted on 11/12/2019)

The item was a one for one swap. It was a very good item that worked well. Review by fred (Posted on 06/09/2019)

Genuine siamp product
This is a genuine part the same as the original. I bought it to replace an identical one that is fitted in my toilet that had stopped working. I was able to unclip it and clip the new one in place without having to dismantle my toilet. Very easy to fit. Review by Nick1974 (Posted on 29/03/2018)
