chuckle, you should see the size of hole in kitchen ceiling if you think that's bad

hi,

yes i can see it's black and coming from heating system but i'm surprised water is so clear in the rest of the system , upon reflection i guess it doesn't take much silt to turn water black. i was hoping to re-use the vent pipe but maybe that's dirty inside and should be replaced ?

hi , no that round tank is the old water tank that got replaced but was too large to get down the loft hatch , i have been using it to store water . i don't understand how black silt has been getting into f and e tank , last time i cleaned it like new and used dettol. yes one time i did have...

any advice welcome

i have seen that leathery slime in tank before after boiler was replaced, that white/grey fungus type stuff maybe from another tank i have in loft that is also contaminated , that is the old water tank that i have been using to bail the f and e tank water into , maybe evaporation has taken place...

hi, i haven't cut the connections out yet but i have removed the f and e tank , the tank had a slime, should i be concerned ? the water in tank looked clear at first but there must have been silt on teh sides of tank because it soon turned black, the tank was immaculately cleaned 4 months ago...

so how can i clean it without cutting it ? i don't really have a pumping over problem now , it's more air in the system i want to sort out and if combining feed and vent helps with that even if it makes system slightly less safe then i'd rather do it. the air vent on water side does collect some...

i want to combine the feed and vent if possible , it will end up simpler and easier for me to do, as long as the system fills ok , the boiler does have an over temp. cut off. one thing that was quite handy is when i had any airlocks when filling i used to blow down the vent pipe and free it all...

if i'm combining feed and vent i may just re-pipe everyting from the boiler rising to the pump, depends if i can borrow a decent pipe bender, there's a poor bend where it comes through the floor into the pump - the bend has ripples/crease marks on it and there's another compression fitting...

so where abouts on the cold feed do they get blocked ? at where i have marked the green circle or the blue or does just everything get blocked ?

i will remove some more of the kitchen ceiling and just make sure which pipes run to the pump. appreciate your help, i will post back tomorrow with some pics of inside the pipes

no all connections are on the flow pipes, it goes : boiler, 22mm vent, 15mm feed, then pump is about a meter away. this is what i'm thinking to cut out :

i don't understand what you mean, here's a few more pics: some of the drawings i have added are not proper photos but proposals drawn using windows paint.

so are these my best options ? what about those elbows on the returns ? is it worth sweeping those a bit better ?
