First thing is never reuse a existing pan connector. You can fit a straight into a bent but not ideal, better to change bent for soil pipe bend if possible.
The spigot will be fitted by you gas Safe installer when your gas pipework is connected up. The spigot comes with the box and 3 screws, make sure they are there.
Hi, sounds like it could have a diverter valve issue. Get a gas Safe engineer to take a look.
As for whether you would be best to have a new boiler, speak to your engineer about the general condutcon of your appliance. Most modern boilers have a life span of 10-15 years but that's only if...
Tbh if BG have replaced a faulty/ worn pump under a service contract then you won't get the engineer altering the position of the pump if the head can just be swapped.
Depends what's been paid for
These systems can be fairly simple in design they just need to be safely designed and installed. I'd take the advise of a good local hetas qualified plumber.m
Nowt wrong with leaving x800 in for a day or two, it stops working after an hour or so tho so any longer us pointless.(it's life is dependant on its use of course) It won't cause a problem either, after an hour it's it's circulating x amount of removed product, after 24hours it's still x amount...
Acid would be best. X800 only works for a short time as it's designed for quick powerflush use. After a day in a system it is doing nothing more. Others last longer but are not as strong.
Calmag do a product similar to fx2 it's only £5 a bottle. Works quite well.
interlock is timed and temp controls that control the boiler. so a room stat and time clock possibly with zone valves dependant on what the system is. Basically the standard controls you would always need to fit to meet the regs. This has been required for many many years not just since the...
Wb filter is made by adey I think, great filter. The CDI classic is a better boiler than the compact. Veissman are ok, think there poo doh smell tho. German boliers = over complicated normal quality.
