Honest Repair vs. Replacement Guidance in Great Neck Plaza
If your Weil-McLain boiler has a sound cast-iron block or intact stainless heat exchanger under 15 years old, targeted component repairs (gas valve, ignition module, circulator pump, or LWCO) are almost always the most cost-effective path. However, if the cast-iron sections are cracked, severely scaled, or leaking through the push nipples, replacement is the safer, more economical long-term investment.
