Cost to install auto feed for water boiler?

[Cliff T.]

Hi all,

My PM found that the auto feed to my water boiler is leaking. The vendor they found is quoting us $895 to install a new auto feed. Any idea is this sounds reasonable?

In case it's helpful, the property is a SFH row home in Philly, approx. 1200 sq ft.

I don't have much experience with the heating / HVAC repairs so appreciate any guidance.
