We have a well and a water tank with a diaphragm. Our water pressure
was getting low, so I checked the air pressure in the tank. It was a
little low, so I added air. At first it was working well, but later
in the day the water pressure dropped to almost nothing. I found that
the filter between the tank and the house was clogged up with brown
crud. I replaced the filter last night and it was OK. But this
morning the filter I put in last night was filled up with the brown
crud and pressure was almost zero again. This stuff must be coming
from within the tank. I've checked the water coming directly from the
pump and it is clear. I think the stuff is probably algae that I must
have knocked loose when I added air.

Right now I have no filter in the line because I think it will
probably just get clogged up again. The tank is 11 years old. What
are ways to solve this problem?

Flush the tank using a water outlet before the filter.

And put at least temporarily a filter in the tank inlet to verify it's
not silt/sand from the well---which is my guess what it actually
is/where it's coming from.

I took a big sample of water directly from the pump and I couldn't see
anything.

I don't think there is any way to put a filter in the tank inlet.

Water that looks clear in a bucket or glass can still have enough silt
in it to clog a filter.

My supply water looks great but I still get dirt / silt build up in
the toilet tanks.

If there is plumbing to the tank from the well there is a way to
install filter......it's just going to take some work.


If you " took a big sample of water directly from the pump " (how
big?)
you could plumb a filter at the same point that you "took the
sample" ....let the water run & see if you clog a new filter

How much water was used between the filter changes?

Your tank "might" be the source of the brown crud but I'll put my
money on dpb's suggestion that the well is the source and putting a
filter between well & tank will verify the problem. Or just filtering
the well output (temporarily)

Unless your tank is "generating" the brown crud how would it be coming
from the tank & not the well? Organic growth? Infiltration?

cheers

Yes, but that isn't something I'm able to do.

Half a gallon in a clear glass container.

Well, I took it from a hose faucet at the pump. There is nothing
other than that.

Not that much. Approximately two baths and maybe one load of washing
dishes and one load of clothes.

I believe it is algae in the tank.

I did what I thought would flush the tank. I ran water through for 10
minutes, then cut off the pump until no water was coming out, then cut
the pump on for 10 more minutes. I haven't tried putting a filter
back in the canister yet.

There isn't an outlet there. Right now I have no filter in the
canister. Can I just run the water for a while to flush it? If so,
should the pump be on or should I drain the tank?

I need to describe the "brown crud". Suppose you took brown paper and
let it soak in water and it broke up into pieces about the size of a
quarter. This is what the brown crud looks like, except that it is
slicker than the paper.

It is in flat pieces roughly the size of a quarter. It looks like it
was attached to the wall of something. When I got water directly from
the pump there was nothing like this in it. When I added the air to
the water tank the filter was OK and the pressure improved. Within a
couple of hours, the pressure dropped to almost nothing and the filter
was clogged with these pieces of brown crud. I changed the filter and
overnight it clogged up again with the pieces of brown crud. I think
me adding in the air knocked it off the inside of the diaphragm.

The filter also filled up with brown particles overnight too.

This morning I replaced the filter that got clogged overnight. Today
I did what I could to flush the tank. I went without a filter most of
the day. An hour or so ago I put a filter back in and in a short time
some of the flakes of brown crud are already in the filter. Only a
couple of them are the size of quarters - most are smaller fragments.
