i have a question and would like advice please from any plumbers out there if you dont mind. We are fitting a new bathroom and using solvent weld cement for the waste pipe plumbing joints which some will be under the floor so we cant risk leaks. Have read that we need to clean the joints prior to cementing. What would you advise that is best to use, cant find any pvc pipe primer/ cleaner degreaser in Toolstation or Screfix. Many thanks
