Looking for material suggestions on bilge and bait tank plumbing. I've got a mixture of vinyl braided tubing and a ton of sch. 40 pvc pipe and slip fittings. I would like to go with the braided vinyl tube and eliminate all of the glue joints/ possible leak points below deck. Is this vinyl tubing a good idea or would something like rubber heater hose be a better idea or something else? Thank You

Braided vinyl works well. Don't know why you would use PVC fittings. Buy bronze, it will last as long as the boat, won't crack, and best suited to the marine environment.

The vinyal braid they sell at west marine or lows works fine. Just make sure to secure it correctly and you will be fine. Don't do what my brother did. He was using different kinds of tubing. Long story short is that his boat was filled with like 50 gallons of water at the end of the day!!

If you use plastic fittings, be safe, use MARELON not PVC.

Ok then I'm going with the braided vinyl. The plan is to have a single run from pump to thru-hull and tank to thru-hull and eliminate all of those glue joints/restrictions to flow. Just wanted to make sure that tube was the right choice...thanks again!

A PVC valve to regulate flow on the bait tank would be about all the hard PVC I want to see. Not good below the waterline. The re-enforced flex vinyl is fine for bilge and bait.

Make sure you have a shut off ball valve at your through hulls if they are below the water line and double clamp your hose connections as well.

Sure its just semantics and I mean no offense but a seacock on the thru-hull is the way to go. No HD ball valves please ! :D

Stainless ball valve is at the pickup for the bait tank before the pump. All other thru hulls are above the water line. Thanks for the input you all, appreciated!

No low spots in the discharge from the pump. You do not want an air lock.

Thanks, luckily it's all uphill from the pump to the tank. Anybody have opinions on the cheaper "corrugated" bilge hose?
Don't use it on anything other than drains that are well above the waterline. Reduces flow and its not particularly tough.

Key word,cheaper.Use the vinyl reinforced hose it will last longer.That corrugated stuff tends to split and then you end up pumping bilge water back into the bilge.

I like the sound of that stuff, I think I may run that from the bait tank pump to the tank and the vinyl for all the others. Thanks for the tip!
