I bought a Wickes branded Earlex WD1000 over 30 years ago. Still my goto shop / car vac. It's had one full strip down and clean. The thing just goes on and on. I've two identical combi filters I alternate between. Just hose them off and let dry. Chippy mate has the same one and loves it the same.
Wish I'd bought another when TLC were selling them off.
They sometimes come up on Gumtree etc.
I have run some 15mm Pex/PB inside 25mm galv electrical conduit. This was in the corner of a wall but that was more for mechanical protection against someone deciding it would be a good spot for a shelf bracket. It'd be a bit moot if someone decides to use a Bosch multi construction bit!
It needs sorting once and for all. The tree has been cut down and shooted / regrown before. The neighbour at one time was a bit against doing anything as it "was a lovely tree".
I like the idea on YouTube. Drill said holes, fill with vegetable oil over the course of a year...keep it dry...then 🔥
I reckon diesel would be better...
