Hi All !
I have a wellpoint with pump hooked up to the garden sprinkler system.
The problem is that I live in a sandy area and a lot of fine sand
comes up with the water, clogging up the water jets. I've fitted small
in-line filters, but these block up in only a few short hours, and
besides, the fine sand get through in any case.
The local hardware stores have been unble to provide solutions - could
only suggest "very expensive sandtraps".
I'm looking for an easy solution, preferably DIY. Anyone out there
who'se had the same thing and solved it, I 'd like to hear from you.
Thanx in advance.

Which is probably why there is the sand. The well is going dry.
Until it drys up, try a soaker hose, that wont clog as easily.
Otherwise I think you're screwed unless you want to spend lots of
money or have a new well drilled.
they make an inline filter that has a clear bowl, it
lets the sand settle out, and has it's own built in
screen. the beauty of this filter is it has a 1/2
threaded fitting on the bottom of it. you screw on
a 1/2 ball valve, and when it fills 1/2 full, you just
open the ball valve for a second, and whoooosh,
the sandis gone. in rare cases you mayhave to
add a secondary, small micron filter to polish the
water, but usually not. the internal screen can be
removed to scrub and clean. I wish I had a brand
name for you, but I don't...consult any plumbing
shop, they may be able to steer you in the right
direction. they are wonderful for sand problems.
Hardware store is the wrong reference. Go to an irrigation supply shop and
buy a "Banjo" filter. Make sure you know your irrigation supply line
diameter so you don't buy the wrong size. The filter element is a cone
which can be removed and back-flushed. You'll also need appropriate
couplings to install this into your PVC irrigation line downstream from the
Especially if this is a new well, let the system run through the hose bib
next to the irrigation pump to flush sand and debris out of the well. Run
it until the water comes out clear and clean -- it may take half an hour or
more. Then, close that fitting and run the system normally. Check and
fllush the filter, first on a daily basis, then as the system requires,
weekly or less.
Since you're under water restrictions from SFWMD, you're probably only
irrigating once a week anyway, right ?? Regards --
Perhaps a different kind of sprinkler would be less prone to clogging
up. I am guessing you have one of installed systems, don't know much
about those, but I know for the end-of-the-hose type sprinklers there
are a lot of different designs and some have bigger holes than
Perhaps you are /have the wrong type of grass for your area. There are

I pulled up my intake tube a foot and stopped getting sand. YMMV. When your
water table gets low, you may have to lower it again to pickup water. Don't
do what I did and stick the inlet into the gunk at the bottom of the well.
It will very happily suck up rocks and sand and gunk. I ruined the pump -
jammed the impeller, but not before grinding some serious groves in it and
causing the baffle to warp out of shape (it was already warped, this was all
it took to cause it to actually come loose). Easy to fix with a $35 repair
kit, but I didn't have the time so I ended up buying another pump.
