2001 Weekender 225 water system

[Robin Kennedy]

Just bought this boat and joined here! Question: how do I drain the fresh water system? The manual just mentions but doesn't say how. Pump works, water comes out the faucet, but they out antifreeze in the toilet and in the sink, and I don't know how to drain the whole system and start over. Help!?

run faucet till it runs dry- refill tank -repeat till runs clear.

Ok! But where does the water drain to? We saw the ice chest behind the sink fill up.

Not positive about your model boat but most sinks either drain directly overboard or into a sump box or sump pit in bilge.

The drain in the ice chest is small in diameter and there is no vent line in boat sinks like yours. The flow coming from the faucet is faster then the drain can allow.

I'm sure you already noticed this as it's very easy to see, but in your boat, the sink drains overboard on the port side. Just stick your head over the side and look. Or, look in the owner's manual - this is typically in there (can also download it from SR's website).

Another possibility is that the line is clogged. If you look under the sink, you'll see you have really good access to everything if you wanted to take the hose off. Or, try hot water/compressed air.

If you do the compressed air thing, the trick is as follows: A helper blows compressed air into the thru-hull fitting as you stand above the sink, looking directly into the drain so you can monitor it. Also... please setup your phone to video tape the process and post it here.
