Can the service entrance wires be spliced inside of the main panel when they might be too short to reach the lugs.

I used ABS pipe. Today I installed the manometer and it read 1.5 inches. According to Fantec that translates to about 46 cfm for my model fan. Does this sound about right for a fairly tight and intact 1200 square foot basement slab? Thanks for your replies, John

I installed the pipe before they poured the slab. There is 6 to 8 inches of gravel under the slab. The sound in the pipe is a rushing rather than gurgling sound.

The cfm of the fan is 157 at 0 inches W.G. . It sounds like for one reason or another the airflow is too high. Maybe an opening in the system some where. I have a gauge to measure inches W.G., but I haven't installed it yet.

Hello, my name is John and I am new to this forum. I hope some one can help me with a small problem I have. I recently installed a sub slab depressurization radon mitigation system in my house. I am using 4 inch PVC from below the slab to above the roof with a Fantech HP fan inline which is located outside of the house. All is well, but there is a very noticeable rushing air noise in the 8 foot long pipe section in the basement which starts under the slab and exits out the rim joist. Is there some way to cut this noise down? I was thinking of wrapping the pipe with insulation but I don't know if this will work, or if there might be a better way. Also, even though the fan is located outside the house, I an still here it on the inside. I have it isolated with rubber connectors, but it is still very noticeable. Any help for that? Thank you in advance, John.
