I have a leaky valve in a pipe that moves hot water to a baseboard heater (I think). These pipes run along the ceiling of the basement. I've included two pictures to better illustrate. the first valve (closest to the boiler) is a straight-up gate valve, the second is a gate valve with a spigot. that has a boiler drain tag on it, but it can't be as it is situated above the boiler. Between the first valve and the boiler there is not other shut-off valve. I think I just need one valve and I would rather that be a ball valve. I suppose the spigot/drain is there in case I want to bleed that specific portion of the heating system, but that entire heating system gets done from a single point, down closer to the boiler. It almost feels like these were added as an afterthought, though they preceded my ownership. So my question is can I cut out both of these valves and replace with a single ball valve? And if so, does it need to have a spigot/drain? Plumbing isn't my strong suit, so sorry if there's an obvious answer here that I missed.

Hi, I'm replacing a toilet. I've always used a wax ring seal, and never had a problem. Now I see a new polyurethane seal that's supposed to be the latest and greatest. I'm looking for opinions- anyone used one? Thanks, Steve
