Black bits in the water

[canalrunna]

Can anyone tell me why we are getting black bits coming through both hot and cold taps.

The tank is stainless and the pump is a Jabsco Par-Max 2.9 model 31395-0292.

Thanks in advance

any pics?

Bacterial growth? Treat the system with bleach or Milton (which is bleach...).

The pump labours and loses pressure momentarily when a tap is turned on  and it is slow to switch off.

Sounds like the pump is breaking up? Is it bits of rubber?

 Muck in the tank picked up from last water top up?

You'd be surprised how much stuff there can be floating about in the water supply - and even more from your hose(s).

Have you pushed ice through your hose at any point? It has an abrasive effect and strips the inside of your hose of any nasty build up.

The hosepipe is the flat type which is quite awkward to get anything down it

Mrsmelly, the bits coming out don't seem to be rubber so I will give bleaching a go.

Have you checked the pump strainer to see if that is full of crap

[BWM]

That looks like scale from hard water, does it have a crisp or gritty feel to it?

This sounds like the problem, my strainer was full and the water stopped completely.

Brian, Is the pump strainer found inside the body of the pump

It should be attached to the water pipe inline with your pump.

Looks like this.

See posting above with a photo of one type, others clip straight onto the pump inlet

Cheers Brian, I will check it out

Use a maximum of 15ml per 5 litres thin bleach (not thick bleach) added to a full water tank to sterilise the water system. Run some through each tap so that the taps and pipework are left full of the water/bleach mix then leave for 2 hours. Drain the tank, and rinse thoroughly by filling and draining a couple of times.

For best practice, do this on a slow water point blocking a flight of locks during Easter weekend.

Either on the Llangollen Canal, the Middlewich Branch or any other honey spot.?

I think BWM is right.

[Guest]

It certainly looks more like limescale/hardness than 'black' from the picture above. Are you/have you been in a hard water area?

 

Particularly if your hose is one of those flat types it could well be that expanding it has dislodged hardness from the last time it was used.

 

[canalrunna]

The hose is a flat type and I have pushed paper towel through a few times with the water pressure and I have been surprised how much crap came out. I have also used a couple of bottles of Milton in the tank, left it a couple of hours and flushed through and the black bits seemed to have stopped? 

Thanks everyone for your help

Buy a proper hose. Just sayin like.
