I am who I say I am a no tricks or dodgy credentials!!! Honestly. Female 60 yrs old, 3 grown up kids 1 adorable 10 year old granddaughter very active, love DIY don't do plumbing though. Electrics, well not a lot just change plugs and rewire small appliances. I was a daddy's girl, still have some of his tools although not much good now keep them for sentimental reasons.
2 plumbers couldn't solve a frustrating problem so went to the library got 2 books read both chapters on gravity fed open vented systems, trawled the internet and spent quite some time in the loft with a stool and a reading lamp.
Did the same this summer when I wanted to lay a few pavers and build a small wall.
Picked up a lot of tips up when I worked in the old YTS most of my colleagues were men. A joiner, bricklayer, welder, painter & decorator, engineer and construction worker. The joiner taught me to cut and scribe so I could fit dado rails skirting boards and fitted wardrobes. In return I did their wives sewing projects. The plumber left just before I joined but he was the one who put in the system 15 years ago and made it work. Had two of our YTS lads with him.
It wasn't rocket science to work out. A system that has been very efficient for 15 years and suddenly isn't anymore after fitting a new cylinder..... trace it back to the cylinder and the guy who who fitted it!!!!!
If the first guy had done his job I wouldn't have bothered just paid up happily for a job well done.
Do some research every time I have to call in the trade to fix something I can't do ( except with plumbing it is usually an emergency and there isn't much time). Had a lot of cowboys over the years. Find a good tradesman hang on to him.
You guys and gals were very helpful thanks.
