I agree... I found the stockman worked better for me,

Glad you got it running

thanks!!! i did the Durso standpipes today and they are perfect!!! except the noise....they ARE making a little noise. the size of the hole in the cap is .154? i dont know if thats mm or what but thats what it said under the bit itself. Its a #23 bit if that helps....anyways, is it possible to make them quieter???

you have too much flow going thru your durso pipes, that is why you are getting the sound, noise. THe only way to fix this, is to back down your pump with your gate valve or ball valve or get a bigger overflow pipe. Basically you would have to go with a bigger hole diameter.

Is the water level going up and down in the overflow? and makeing a lot of noise? I would add a johnguess fitting at the top of the Derso that way you can adjust the air intake. It helps a lot with noise but yes asmodeus is right if you have too much flow no amount of air will quite it down.

good call on the john guess fittings too. I just drill a 3/8" hole and air line tubeing witha small air valve ...

no, the water isnt going up and down. everything is running perfectly BUT the noise. Nothing will quiet this down???

if you would read then you will understand

try the JG valve its all about mixing the right amount of air and water flowing down the pipe... The mag 18 is probably only doing about 1000-1100GPH which shouldn't be exceeding 1 1/2" pipe

well, i have 5 days of successful running but still cant fix the noise....i turned the return pump pretty much all the way down and it still made the noise??? i dunno what to do, but lets look on the bright side...NO LEAKS IN SIGHT!!!!

Is the noise coming from the Drains. Is you can pin point the sound , I' trying to remember. Oh by the way i will see if i can come over som time this week ok.. I'm allowed to sit
