Hi. I'm a newbie to RVs. When I check my anode rod and attempt to flush the white stuff out of the tank with a garden hose, water floods inside the RV and I don't understand why ???? Can anyone explain please.

Hi there may be a couple of reasons.
The front fascia piece fits inside the front of the HWS, which leaves a gap between the two, water flows inside and on top of the floor which is inside the van.

Other may be the sheet metal hole the anode fits through may also let water inside.

I silicone this front lip and about 50mm up both sides and it seems to stop the leak.

Side note Amazon USA sell a flush out tube which fits to a hose fitting with a little bend on the end to help get the white stuff out. Could be made with some plumbing fittings and a small dia rigid tube?

Regards John H

Yep you were absolutely correct - I found a gap under the hole were the anode fits through and that's where the water was flowing through into the RV. That gap was enlarged by some corrosion as well. I have sealed the hole with gap sealant and that should fix the issue. Thanks for your advice. Regards, Paul
