It’s definately a M6055,
Look like an 80’s relic, completely biege and brown!!!
However it was free, so I cant really complain.
My landlord sent a plumber round to fix a leak in the bathroom a couple of days ago, and it’s only since he’s been that the issue has crept up.
I’m hoping that the pressure has been reduced as a result of something he’s done whilst playing with the pipes (no pun intended), in which case I can get him to sort out the problem he caused.
Thanks again for your help
