Captains,

It would appear my hot water heater is leaking. Pictures attached:)

It appears water is spraying from the metal relief valve and it still has the plastic drain valve as shown in the pictures to the left.

If I leave the pressure washer on, it will drain the fresh water tank. Boat had 335 hours on it 2 years ago and it has 450 on it now, so low hours.

This is the Seaward brand and probably what came with the boat.

So here are my questions?
In the forums, some people are replacing both valves with brass versions.
Does this solve the leaking pending the weld has not spilt?
Or would you just replace the whole unit since it is 22 years old.
Is there a tankless version I could go back with instead?
Is the Seaward brand okay?
Do you have another brand that seems to hold up better?

The pressure washer appears to rattle on the board underneath the aft cabin bed, but in my opinion, it appears the screws have just backed out some. So I am going to tighten them down and check the noise.
How long do these last and is it wise to replace both the pressure washer and hot water heater at the same time.

I will be replacing these myself as I have been a automobile service manager for 25 years. I love tinkering and repairing issues gents.

Your thoughts please and this is a 1998 405
