 beveled washers or flat washers
Author: Larryr (MN)

I plan to replace faucet washers on my bathtube. The seats are the standard brass replaceable type. What determines if faucet washers should be beveled or flat? Is any washer material better than others for life use, and seal?

DH is most correct. Most bibb washer are flat. There seems to be a prevailing logic that a bigger bibb washer is better than a small flat washer. That is not true. By installing a beveled bibb washer, your stem now has less room to travel and that could create additional problems.

Follow DH's suggestion and use only factory original repair and replacement parts (OEM)

Best Wishes

95% of (compression type) faucets that I rebuild use flat washers, made from neoprene
rubber - although some stems need to have beveled washers installed for a proper repair.

For best results, replace both seats as well.

I always use beveled, unless the movement of the stem is so restricted that a beveled one would not open fully.

With all due respect for your years of experience, HJ, what do you think the advantage of a beveled washer would be, especially when the original washer is flat?

i agree with greekguy. when you use a beveled washer on the hot side, the heat tends to swell the washer and slow down the flow. plus, i find the bibb screw tends to come loose as the beveled washed is compressed more than a flat washer.
i rest my case.

The bevel has a better chance of conforming to the rounded seat face, thus making contact over a greater area. The flat washer will only mate to the upper surface. Besides, the greater thickness of the beveled washer means that the washer will last longer.

Or be torn up jammed into the seat!

All it takes to stop water is 2 flat surfaces...

I think HJ's alone on this one... Most of the times that I find beveled washers installed is when the previous repair person could not remove and replace the seat and thought that a beveled washer would last longer before the faucet needed another repair. A beveled washer will also get squeezed out of the washer retainer compared to a flat washer which will remain tightly in position.

Seat surfaces are not "flat". And if you remember your Calculus, a rounded surface is flat, but for only a microscopic distance.

No way. The edge of the beveled washer is the same thickness as a flat one, the extra material is at the center where wear takes place. You are letting your preconceived notions rule your thinking.

Actually it's not a preconceived notion of mine, it's solid evidence. When I take apart a faucet, I sometimes find that if a beveled washer was used, it is 'squished' and is larger than the opening in the faucet where the stem passed through. That wouldn't happen with a flat washer >as often as it would with a beveled<.

"as with both of those it is really a personal preference"
it is not personal preference with me. i have to admit, i have had leaks/problems with basket strainers, shower strainers and pop-up wastes when i used putty.
BUT, since switching to 100% silicone, i have NEVER had a leak. now that some (not all thankfully) shower strainers and lav pop-ups are coming thru plastic, you can't tighten them enough so you either throw them in the trash or silicone them.
i rest my case..

you prefer to use sillycone because you do not know how to properly use putty.:P

no matter how you say it, it is still a personal preference since either will work

You must have 600 pound gorillas for customers, because I have never seen that happen. My customers turn the handle until the water flow stops, and eventually the washer wears away as the seat penetrates it. In fact, Price Pfister faucets used to come with a modified beveled washer that was sort of cycloid shaped in cross section.

Larryr...

Between beveled and flat washers, I try to use what was originally in the faucet. In general this gives the best results.

TIP: In the past I've had to revisit several faucet repair jobs because the washer screws were coming loose. Over-tightening these screws caused other problems. I started using a drop of superglue to "lock" the threads and the screws no longer worked themselves loose. Problem solved.

For those that think superglue is something more than just plastic (cyanoacrylate ~ acrylic), the screws are easily broken loose with a screwdriver if future repairs are needed. There are many variants of superglue specifically designed to be thread-lockers, but I find the common stuff works great and is the most useful to carry around in my toolbox.

As for the silicone vs. putty debate, each material has pros and cons depending on where they are to be used. People should be flexible enough to use the best one for the job in front of them.

Good Luck!
