I'm in two minds here..... I DIY most things.... rewiring (before it became illegal

) plumbing, tiling, flooring etc.
Yes it's a lot of bother but at least you know the jobs been done properly.
Of all DIY activities I dislike plumbing the most... usually because there is no standardisation of fittings.
But I still 'do it myself'
It's cheaper
.....and I don't know how to find a reliable plumber.... when we had an extension built we kept in touch with the plumber that the builder used and we got him to do a couple of jobs. When he fitted a new handbasin he fitted the waste incorrectly so that the overflow didn't work (and of course we only found out when the floor was flooded).
So if it was me I'd just knuckle down and do it.
