Plumbing Vent Caps On Roof --- All Sun Broken & Ruined

Finishing up a bunch of maintenance on the 8 year old 5ver. Last thing was to get it washed. While up on the roof washing noticed all 3 plumbing vent caps broken and really deteriorated bad. Just the caps are rotted, bases seem OK. Went right on to Amazon and ordered a 3 pack of the Camco replace all plumbing vent kit. https://smile.amazon.com/gp/product/B00IOXKA3W/ref=od_aui_detailpages00?ie=UTF8&psc=1 I'm just going to use the caps and keep the base in case I ever need to replace the whole vent.

Question ---- It will take up to 10 days to get them delivered and we have the possibility of some thunder showers coming in. If a substantial amount of rain goes into the now open pipe does it all just go into the gray or black holding tank or is there something else I don't know about that could cause damage?

  • Do you have attic vents? Mushroom shaped caps and about twice the diameter of the plumbing vents? I replaced those this year as the old ones were chalky and starting to deteriorate.

    Just thought one vent may be for something other than plumbing like refrigerator vent or such.
