I own an sealine S25 the problem i have is i use for overnighting the next morning the carpet is soaking as water is coming up through the floor this only seems to happen when weight is used down below any ideas ty....
check your shower over flow box . every time you use hand basin [ not all are connected to it]or shower, you put water into it, if its blocked, theres a filter in it,and a bilge pump, it will overflow,
use the manually bilge pump to empty bilges before you go to bed. then check under floor on waking and see how much water there is, something is leaking and you need to trace it.
If there is a leak from your fresh water system,unless its the main water tank or before the pump you would be aware of it cycling all night [clicking] as the pipework is repressurised.
