🦆 Maintenance Monday 🔧

As warmer weather arrives in Northwest Indiana, it’s a good time to check your exterior hose faucets for leaks. ☀️

Even a small drip outside can waste water and raise your utility bill. Catching it early can help prevent a bigger plumbing repair later. 💧

If you notice leaking around an outdoor faucet, siding, basement wall, or crawlspace, Downing Plumbing can help with exterior spigot and hose bibb repair or replacement.

FAQ: Is it better to repair or replace your water heater?

It depends on the age of the unit, the type of problem, and how often repairs are needed. A simple component replacement may be all you need, but if your water heater is older, leaking, or struggling to keep up, replacement may be the better long-term value.

Not sure which option makes sense? Downing Plumbing can inspect your water heater and help you make the right call.

Teach you Tuesday 🦆

Fluctuating water pressure is usually (not always) caused by a faulty pressure regulator, a failing well pressure tank, hidden plumbing leaks, or mineral buildup in your pipes and fixtures.
