Old Shut-Off Valve Replaced with ProPress Ball Valve in North Napa

New brass ball valve pressed onto copper with the old corroded gate valve held up beside it

What was replaced?

A failed 3/4-inch water service shut-off valve at a home in North Napa. The old gate valve was corroded and seized, and could no longer shut the water off.

Why does a seized shut-off matter?

Because it is the valve you need in an emergency. If it will not close, a burst line means shutting the whole property down at the meter instead.

What is ProPress?

A press-fit connection system used to join the new brass ball valve to the existing copper, instead of soldering — no open flame on a live line inside a house.

What does a failed gate valve look like?

That worn-out gate valve in your hand tells the whole story. Corroded, seized, and no longer able to fully shut off water flow - it's one of those small components most homeowners never think about until something goes wrong.

What was the call in North Napa?

We were called out to a home in North Napa to replace a failed 3/4" water service shut-off valve. The old valve was non-functional, which is a real problem. If a pipe bursts or a leak develops anywhere in the home, you need to be able to cut the water supply fast. A valve that won't turn is basically no protection at all.

What is ProPress and why use it?

We used ProPress technology to install a new brass ball valve on the existing copper line. ProPress uses a press-fit connection system instead of traditional soldering, which means a cleaner, faster, and highly reliable joint. No open flame near your home's exterior, and no waiting around for solder to set. The result is a tight, professional connection that's built to last.

Why does this count as leak repair?

It's the kind of repair that falls under our leak detection and repair services - catching a problem before it turns into a much bigger headache. Whether it's a faulty valve, a dripping faucet, or a hidden pipe issue, small fixes handled early save a lot of money down the road.

Why is a working shut-off worth the visit?

Sometimes the most important upgrades aren't the flashy ones. A working shut-off valve gives you real control over your home's plumbing - and that peace of mind is worth a lot.

This job is an example of leak detection & repair in Napa.

What did this job involve?

Do fixture replacements need a permit?

A straight like-for-like fixture swap generally does not, but altering or extending the supply or drain piping does — and in Corte Madera and Belvedere, certain fixture and water meter changes are themselves listed triggers for the Sanitary District No. 2 lateral inspection ordinance. Worth checking the local rule before assuming a swap is invisible to the district.

Can I install a new faucet myself or do I need a plumber?

A straightforward like-for-like faucet swap on accessible supply stops is within reach for many people. It stops being simple when the shut-off valves are seized or weeping, when the supply lines are corroded, when the sink or counter needs modification, or when the new fixture has a different hole configuration. Old, stiff angle stops are the usual reason a quick swap turns into a call.
