Toilet Valve


I'm planning on replacing a few toilet valves.

  1. Should the hoses connected to the shutoff valves be replaced also?
  2. Also, one of the hoses is pex. Does that hose need to be replaced by pex also, or can it be regular braided hose.
  3. Is tubing really for looks, or does it work better than braided hose? How much bend can tubing take?

  1. Should the hoses connected to the shutoff valves be replaced also? YES, always.
  2. Also, one of the hoses is pex. Does that hose need to be replaced by pex also, or can it be regular braided hose. Use braided supply.
  3. Is tubing really for looks, or does it work better than braided hose? How much bend can tubing take? It's chrome plated copper. If you are not going for looks, go braided supply. If you are careful, it will bend quite a bit but you should not go beyond 90 degrees.

Toilet Valve


Is it necessary to use Teflon tape on fittings and what is the general size of the braided hose to be used?

Toilet Valve


Use teflon tape or pipe dope on tapered fittings and pipe. Do not use on compression fittings.

In general, the braided hose is 3/8" with a 3/8" connection on the angle stop end and 7/8" connection on the toilet end. The braided hose should have a tag on it stating either "toilet supply" or "closet supply".

Why is it not recommended to use pipe dope on compression fittings?

Also, I was at HD today, and some lady was telling me her plumbing nightmare about how her plumber can't seem to fix a leak on her shutoff valve on the compression nut side.

Is it true that if you replace that shut off valve, that you will need to cut off the section that the ferrule has made an impression into and start on a new section?
