Couple of bungalows worth of solar panels to do end of week.......I have Ubik 2000 and Synergyclean Pro.....which would be more suitable....or would just pure suffice?

£32? Wow, that’s under-priced.

is it me or are the dosatron chemical injectors super flimsy, I'm referring to the small pipe work that comes out the side of the unit and then joins the outflow at the top, I find these really fiddly to tighten up and they keep breaking. Any thoughts or mods anyone?

I would have told her no problem, £200 because they have not been cleaned since I last cleaned them. Money paid into my bank account before I begin. I always offer old customers my service back but bump up the price. I'm happy to do work at a premium. Received a call from a rich guy saying he only had 12 windows. He texted his address and I saw it was a £750k house. I text back the real price and not heard from him since. I think he bumped the windy cleaner and thought he would get a newbi to do it for a tenner a month or he was selling up. Great getting customers this time of year because we are all busy so give a good price and don't need to explain anything because they need you more than we need them.

How many have you lost to get the 100 you claim you have?

Have you checked the stop cocks in the house and out on the street - maybe not fully open

This.
