No pipe dope on water meter

I watched a town water dept. employee replace the meter in my basement. He did not use pipe dope or tape on the connection of the meter. I asked and he said it did not need it.... it looked like a compression fitting of somekind.

Is this standard?

Thread sealant is only used with tapered pipe threads. The meter is connected with union nuts and uses gaskets to seal.

Below the meter is the main shutoff. Its an older 3/4 gate valve with threaded inlet and outlet. It too is connected with a union at least on one side. None of that was touched in the meter changeout.


Is it normal for the main valve to be a threaded connection?

The checkvalve on the otherside of the meter is threaded too.

Most domestic/residential water piping connections are threaded when it comes to steel piping. Soldered connections are common with copper piping and threaded transition adapters are often used with valves. Most pipe unions are of the "ground seat" construction that seals by means of a coned fitting drawn together by a locking ring; the gasketed unions of a water meter being the primary exception to the rule.
