Just taken the motorhome out and flushed the toilet and black bits have appeared in the pink flush liquid. Probably need to flush the system through any advice on how to do this would be helpful. Thanks in advance

I understand that they are algal growths and can be reduced by using a cistern chemical such as Thetford's pink flush.

the pink liquid is notorious for producing black bits! as you use a flush fluid i assume your flush tank is separate from the main cold water supply in its own reservoir.

our current van does not use a separate tank or flushing fluid so dont have the issue any more. when we did have a separate res we had the same happen. the only way i found to reduce it was to make sure it has no open valves and stick a hose ( on a pressure nozzle but not too strong )in the filler and loose up as much as possible then drain / flush as much of it as you can out.

but IMHO you wont stop it happening again.

On and off for many years.
It's algae growth as already been said.

Milton will do the job but it always comes back. Nothing to worry about really as long as it isn't drinking water. Looks unsightly but won't kill you.

Was a newbie, now a Middie.
