 Expansion tank
Author: RR60 (VA)

A couple questions if you guys dont mind.

I was talking to a plumber that does bath remodels. When he does a shower with multiple shower heads. He adds a expansion tank. Which he states makes up for the pressure drop with more heads.

Is this correct? Does not make much sense to me.


One other question
I have used the poloy washers on tubular pipes under a sink. And never really had a problem. I notice the new standard is using the red or blue silicone washers.

Are they better or worse. I tried one under a vanity. Connect a 1-1/4" tail pipe into a 1 - 1/2" Ptrap. So I used a reducer one.
When I tightened the nut, it pushed the washer all the way into the Ptrap.

Thanks for the advice

interest theory. the principle is the same as a well-trol tank

Never seen or heard or installed an expansion tank for a shower system.

I have had the same problem with the silicone reducing washers that are not solid. Have to be careful not to overtighten and make sure pipe/connections are straight.

The non-reducing silicone washers seem to be a little more forgiving that the poly washer if you are connecting to an old galvanized nipple etc.

If it still leaks you can always just spraying it with a quick coat of Flex Seal ! wink

he said by the water heater. Which I have seen. But thought it was only for water hammer.

water hammer devices works best when they are installed close as possible to the offending fixture.

so, put it this way... the tank doesn't help much but it doesn't hurt either.
