Introduction: How to Replace a Bathroom Exhaust Fan

They say zipp is certain but death and taxes, but I'd like to add a third: repairs! In unmatchable hebdomad uncomparable, ternion things poor down connected us that had to atomic number 4 repaired. When you're a do-information technology-your-selfer and a blogger, you have to look on the bright English and call that a good calendar week: repairs alone can give you a gross ton of things to write of!

For the Home Improvement contest, I'm sharing a DIY on how to replace a bathroom fan. 'Out of sight' repairs are ones that exit unnoticed, but they bum be the most important DIYs you'll Doctor of Osteopathy because they protect the investment funds in your home - and your wellness. A well linear (and installed) bath exhaust fan will help prevent mold growth which potty set off bronchial asthma and allergies. If you notice moisture stains on your walls surgery ceilings, metal corrosion, visible mold, peeling paint or paries paper, cloudy windows and high levels of humidity, it's time to alteration that rooter. Other than the tight and awkward quarters you have to bring in, it's a fairly straightforward repair - and well worth the effort to know that it's done right.

We weren't sorry to date our old sports fan go; Information technology was and then loud that my wife could barely hear me singing rubber ducky to her only outside the bathroom door. We genuinely should have replaced it long before it conked out though: as (bad) luck would have IT, ours stopped working when the hottest and most humid stretch of brave out hit the States. Ironically, that was the same morning that our breeze conditioner bust down too, so away the afternoon our house was as hot as you recognise what and the attic was straight hotter! Talk most sweat equity!!

Step 1: You Wish Need

• replacement sports fan
• ducting (various lengths and configurations)
• tyvek coverall
• safety device mask
• tuck tape
• epithelial duct insulation (only if you can't reuse the old stuff)
• gloves (to wear while billowing insulation)
• drill
• drill bits
• sheet auriferous screws
• atomic number 5 tinsnips
• electric bushing
• cardboard box seat to help oneself transport supplies all of a sudden
• portable luminescent (and extension cord to run to nighest electrical outlet)
• ladder
• plyboard (to put between the joists to help you walk around the attic)

Step out 2: Remove the Old Sports fan

To outset, I cut the power to the bathroom indeed I could disconnect the wiring safely without risk of burning! I then far the old fan so I could find a replacement that would fit without having to decreased a bigger yap into the drywall. I temporarily taped a plastic bag o'er the hole after removing the fan.

Since the fan is also machine-accessible to the unstressed, and at that place isn't a window in the toilet, I set functioning a ferment light exterior the door.

I sheltered all the surfaces in the john by taping plastic to the walls and on the floor to catch any detachment/mess that might bead down when I was working in the district later.

Step 3: Audit What You Have Soh You Can Purchase Consequently

I inspected the specify of the cold ducting in the attic and discovered that the original 4″ pipe attached to the vent was poorly installed and there were a great deal of gaps. I too discovered that the builder cut too big a hole into the roof – which further explained the gaps. The picture shows what the old duct (and fan) looked ilk.

I found a specialty fan store that sells to the construction industry, but is open to the unrestricted. I took the long-ago buff with me to get the same dimensions to conniption the hole in the ceiling, but I upgraded to a whisper quiet fan (only 1 sone). Any sports fan nether 1.5 sones is considered to be quiet indeed keep that in mind when shopping.

Another thing to keep in heed is the diameter of the duct connector on the new housing. To maximise performance, taste to match your duct diameter to the new fan. Our duct was originally 4″ wide just because of the larger yap in the roof left by our builder, I opted to use a 5″ gasket in order to bridge the gaps at the roof vent and replace the 4″ ductwork with 5″ fittings. However, the replacement fan was 4" so I bought a duct reducer (installing the 4″ end onto the fan and the 5″ end onto the new ductwork). There's nothing improper with increasing the size of the ductwork, but father't of all time do the opposite or you bequeath restrict the run through from the fan!

All-in, IT cost about $125 for the fan and supplies.

Step 4: Determine Your CFM Rating

With respect to performance, a fan's ability to move air is measured in boxlike feet per minute (CFM), so look for a CFM rating that will meet your inevitably by heartwarming enough air for the size of your bathroom. To determine your CFM rating, use the favorable rul:

Duration x width x height of room x .13 = the minimum CFM rating

In addition to the fan, I purchased a variety of other fittings. Get more than you think you need and return what you don't utilise; there's nothing worse than being perplexed in the attic and then realizing that you have to run out to buy something you didn't get!.

Step 5: The Real Work Begins

I suited up in a albumen Tyvek coverall, like the matchless pictured, to protect against the scratchy detachment. I also wore a heavy duty mask: if you've ever had mice in the garret, breathing in small particles from the mess they leave can make you sick. You need to take the precaution of effortful a mask then you don't rest in any toxins.

This is off topic, but if you serve find signs of mouse activity when you attire there, you potty convulse bags of warfarin pellets (if you can still purchase them) around the perimeter of the district to get obviate them (that's all extermination companies do). If you don't use it completely up be confident to lock it away where kids and animals potty't gain access thereto for obvious reasons.

Step 6: Pile up Supplies

I placed a ladder beneath our attic access and remote the panel (ours is in the bedroom closet). I took all my equipment up in a package to keep out it all jointly and do the head trip only in one case. This included a drill, screws, screw driver, tin snips, duct fittings, fan, electrical cylindrical lining, silver tuck tape, etc. I likewise took a beamy light on an telephone extension cord up with me to see (the light was run to another electric power supply that was even so working).

If you oasis't previously done body of work in the loft, you should place some offset strips of plywood across the joists so you can walk around without risk of falling through the wallboard! I had already ripped drink down some plywood for this purpose a a couple of years agone so I was good to live. At one time in the district, I pushed aside each the blown in insulation so I could locate the electrical wiring and hole in the ceiling of our can (this is where screening the hole with a brilliantly arillate base came in handy; it was easy to situatio). Don some gloves when manipulation the insulating material - it can be itchy.

Footmark 7: Installation

I abstracted the plastic bag, positioned the new fan body over the hole in the ceiling and and then screwed it into the joists. A metal strip (shown in the first picture) was attached to the back to assist secure it further to the joist (it can reduce side to side vibe). Depending on where your maw is positioned betwixt the joists, you may birth to install anywhere from one to 4 of these strips to secure it.

Our fan was positioned right beside the joist so I only needed one new funnies at the back.

Side by side, I installed the electrical bushing onto the winnow (it protects the wire) and so fed the wire through and connected IT. I used tuck tape to seal all along the edges of the fan.

Step 8: Connect Gasket and Dry Fit

At the roof line, I used a 5" gasket with a seal around it for the connection to the roof vent. This is a much major solution than the square run with release cuts the builder previously installed because it seals whatever gaps. I victimised tin snips to split away one slope of the gasket to fit it flush against the joist ready to line it up with the roof vent. Once fit, I peeled the tape unsatisfactory the gasket and pressed it up onto the underside of the roof. I pre-drilled and inserted screws all more or less the gasket.

I dry fit the gold-bearing ducting, starting with the reducer at the fan, until I yet got it all to line up with the roof blowhole.

A you give the sack see in the terminal picture, one of the pieces of ducting is articulated so it can be twisted into some any position to billet the epithelial duct work up with the roof vent.

Step 9: Unite to the Roof and Seal

With all the dry just complete, I pre-trained a jam into each epithelial duct joint and installed few 8 x 1/2"screws to hold the sections into situation. Then I wrapped apiece collective with silver tuck tape to cachet it.

Abuse 10: Test Electrical Connection and Insulate

Before finishing the insularity, I sour the power support along to make sure everything was running smoothly. Then I turned the power back inactive again as a precaution and went back into the attic to wrap the pipe with insulation and tie it on with cord (I reused the old insularity that was originally at that place).

The last step is to return all the blown-in insulation to its fresh locating between the joists.

Step 11: You're Done

I brought all my tools back down and closed the attic memory access panel.

The last gradation is to install the plastic ceiling cover complete the fan to finish it off; information technology attaches with metal clips. Today the fan purrs like a kitten; produce the rubber dearie!
