Block drains

We started to get ready to go out and do our calls, but then the shower started to back up and ten years of hair balls floated up, bathroom sink to blocked up, , found the 4" outflow from the house was blocked up near the ditch in the grass, cleared that, nasty'ness came out  but shower tray still blocked, I tried plunging it with a mop, no success then managed to get a pipe off outside, and rodded it with a thick hosepipe, still no success, then Abbi downstairs, had water dripping off our pipework that goes through her bathroom downstairs, I decided to renew an elbow fitting, so biked off, it then decided to rain, got the bits, rained on way back too, stopped raining when I got back then found out there's at least two types of solvent weld 1 1/2 pipes on the house, fortunately it changed to the right type by the elbow, found similar size pipe in the stores under the outside stairs, replaced it, gunged up older joints, and hoped for the best.
Everything here is badly built and unless you rebuild the house, you just do what's necessary to get by.
But adds to the experience, good news we didn't catch any germs,
