Contractor just installed a Maytag MED 5500 FW dryer. The 4"

Customer Question

Contractor just installed a Maytag MED 5500 FW dryer. The 4" vent line is at the maximum length accounting for elbows. Near the end where it exhausts horizontally, he has increased the size of the vent to 6". Will this increase in size make it difficult or impossible to clean adequately? will lint just build up in the 6" portion?
JA: Can you guesstimate how old your Maytag is? And just to clarify, what's the exact model?
Customer: Brand new never used yet. I don't have more than MHW5500FW for model number. It is side venting.
JA: Do you plan on doing the work yourself?
Customer: No. proper installation is contractor's responsibility.
JA: Anything else we should know to help you best?
Customer: If this size change is a problem, Are there any cleaning methods that could reasonably be used to keep it clean, or should we correct the installation and use 4" vent (smooth, not flexible) full length?

Yes the larger 6 inch venting will not allow the dryer to have the correct back pressure,, so any lint that has gone thru the filter and the full length of the 4 inch vent line will just stack up in the 6 inch vent and eventually clog the vent

Now if the venting pipe has to be that long if they install a vent booster fan on the dryer vent piping then it would work fine.

Lint would eventually clog up the 4" line also if not cleaned periodically anyway. Will normal cleaning correct this problem or or is there another reasonable way to clean it with the 6" portion? Do we need to change back to 4" vent full length? No room for booster fan.
Expert:  Whrlp Master Tech replied 9 months ago.

You could run the dryer for 20-30 years if the four inch piping is run correctly before it would clog up.

yes I would change the 6 inch to 4 inch , less likely to have an issue.
