Over the last couple of years, I get ocasional emails about pulser
pumps for different locations, I give out info, and wait for the pics
of the pumps or pump models (Which never have come).
Whatever. Thats how people are, I guess.
Anyway, the pump i made long long ago is still working.
I think I made it in 1988. I assumed it stopped working a coulple of
years back because they built a shed almost on top of where the pump
is placed. But it didnt. I mentioned it to my sister today when i
foned home and she said they used it a lot this year.

Things have changed a bit since the late 80's and my brother Neil
installed big rain collectors in the sheep shed so mostly they fill
enough over the year to tide the sheep over. February was dry so he
used the pump a little to provide for them but mostly he has used it
to send water to his cattle housed in a different shed. (cattle in
ireland are often housed in the winter months because frost and rain
and cattle feet tear up the ground a whole lot).
Anyway, my sister Miranda said it has been really useful this spring
for sending water to the cattle! So, it might make 20 years in
service! not bad for about 25 feet of 4 inch diameter pipes, a swept t
joint, about 20 ft of 3/4 inch pipe and a waste 5 gallon plastic
formic acid can!
No moving parts is a pretty useful attribute,I think.
Have a good day,
Brian
