I'm wondering which plumbing issues on the 1896 house I'm purchasing need to be taken care of right away (and which are not necessarily issues). Some background on the house: it's on the far northern California coast, where freezing pipes are not an issue (nor is excessive heat - the summer highs are in the 70s). It's a Victorian on a post/pier foundation, with a roomy crawlspace beneath, so repairing pipes shouldn't be too hard -- right?? Here are the inspector's notes in blue, with my questions in red:
Galvanized. Appears serviceable. Looks like a valve from the city side is leaking. However the meter is not running because of this leak. I'll call city about this, but should I be concerned about lead from the main line?
Plastic. There is very poor support for supply lines. CPVC lines viewed at exterior, but underneath the house they turn to PVC, which should not be used under houses. A contractor said that PVC is fine here since there's no chance of them freezing. Also, how does one go about supporting the supply lines??
Galvanized and black pipe. Appears serviceable. What is "black pipe"?
Cast Iron and Plastic. P-trap for washing machine standpipe is under floor. Supposed to be above. Also, no vent viewed for same trap which can allow the trap to be siphoned dry. This allows sewer gases to come back up through the drain.[COLOR=red]How difficult will this be to fix? Black ABS vents exposed to sun on north side of house should be painted with white latex paint to deter sun damage.[/COLOR]
Temperature-pressure relief valve drain line is too small and is crimped in places. Vent cap for water heater is too close to kitchen window and and could get into house through stove hood fan vent. The crimped pipe sounds bad, but it's outdoors and accessible -- easy to fix?? Is the vent cap thing just being overly safety conscious? What could happen other than fogging up the window?
Thanks in advance for any opinions!!
