this week my solution tank has become dirty with a mushy substance floating in the water, eventually clogging the intake filter. i can't seem to find the source so thought you guys might have some ideas.

i very very rarely use an alkiline in the tank, though about 1.5 weeks ago i used some prochem double clean as the carpets were just disgusting. i typically have a acid rinse in the tank, and thought perhaps over time the pump and the pipe have a layer on dirt on them which the alkaline has loosened? though the pipes don't seem like they have much dirt in them.

if this could be it, what would be a good way to clean out the pump and pipes?

if not this, any other suggestions?

i only ever use one bucket for filling the tank, which is always rinsed before each use.

At a guess I would say it must be a build up of crud, did you buy machine new?

[Adam P]

yeah was bought new about 5 years ago.

[scott johns]

do you ever descale your machine and pipes, are you in a hard water area? all could contribute towards build up of dirt
in your tank we always fill machine up then add detergent to very hot water to easier dissolve powder.

[sean oregan]

I would go with Scott and descale machine

[Adam P]

how do i descale? I very often use an acid rinse, figured this descaled it as it goes?

i've also got a magma heater. is that worth descaling too then, even again if it's only used with an acid rinse?

[sean oregan]

Before you do anything I would give Matt or mark a call, they are very helpful

Is the machine in daily use?

It sounds like what I get in my bowser when it's been sat awhile with water in it, a scummy Algae growing on the water.

Scale would'nt cause what you describe .

[Adam P]

almost daily use yes but there are some rare occasions where it's not used for 3/4 days, which i guess thinking about it, happened recently.
