Replacing a gas fireplace key valve question

its a code violation to have a flex pipe in an inaccessible location like inside a wall and will void your home insurance in case of a fire or gas accident.

as far as the valve replacement, i would assume it has to be unscrewed from the fireplace side and then slid out of the way so you can unscrew the valve.

call a plumber that does gas lines out to do it, its what they do, and then you can discuss what your different options are if you have any.

maybe he can relocate it to a better place for you to access

You can do it, but yes it’s a code violation. You might not be liable now but if you sell the house you’ll have to correct it. I’d do it correct the first time or hire a plumber

Banks require a Home Inspection. Those inspections are read. In most cases they affect something the owner and buyer need to negotiate and don't have an impact on the risk.

Code violations regarding Gas, Electric and Plumbing ....especially home owner created violations require notice that the mortgage company takes into account because it may affect the risk they about to take on.

After hundreds of inspections I've conducted....there a small percentage of things I've discovered along the way that caused loans to be declined.

Banks don't read the inspections ....I've had Bank Loan mangers call and tell me they need clarification on a note before a loan was processed.

The biggest hit on one of my inspections? I received a recall notice on Square D Circuit Breakers on evening. A year warranty inspection was conducted the following morning. When I pulled the panel on the circuit box and checked the wiring and the circuit breaker numbers every breaker in the panel was in the notice. The breakers would not trip. Foreman was called, he and I looked at the breakers, he called the electrical contractor and realized they had 100 homes with bad breakers. We all knew the if the City Inspector was doing his job, he had the same recall notice I had and would be failing houses with those breakers.

I can't help it that most Residential Inspectors aren't worth spit. I can't help it that Bank Lenders put the new owner at risk because they don't read. A home fix that violated code intentionally is not worth risking your families lives over.

The banks and Realtors I worked with wanted precise inspections not half assed.

It depends on the loan type. FHA for example requires an FHA type appraisal.
I’m happy for your number of inspections, I’m just saying inspections are highly encouraged. The dozen or so properties I have purchased I don’t recall the loan officer asking anything about the inspection report or does one exist.
