Hi,
I was given an
Iwaki DP20 (suppose to be similar to RD20) and it works great. The head pressure is strong. The only downside is the noise level. It sounds like my neibhbor is mowing his lawn. You know, sitting in your living room and listening to your neighbor mow his lawn. I looked all over the forums but found no suggestions on how to lessen this noise. I was thinking it could be air in the lines but didn't find any bleeding screw.
Any ideas? I like the pump but its driving me nuts.
Thank you,
Dave
