Hope this isn't a dumb question! Is it possible for water from a toilet tank or bidet tank to move backward into the home's water supply? I saw backflow preventers to be added to the toilet supply valve advertised lately but I have never seen such a thing in use, so it led me to wondering, is...

Hello guys, I wanted to use a quick disconnect to attach my garden hose to the spigot but I found it cannot work with the vacuum breaker device that is on the end of the hose spigot. The two devices bump into each other when you try to clamp the hose part of the quick-disconnect into the spigot...

I would like to put in a bidet seat but I don't have a circuit free to power heat in it. The refrigerator circuit is right on the other side of the wall. It's 20A and includes a couple of rarely used GFCI receptacles. I could come off one of those and bring an outlet to the bathroom side of the...

I tried an acidic toilet bowl cleaner (I used EdFred) and found that it worked so much better than the ones available at the grocery store. I'm wondering why they aren't all formulated like this? I want to switch to this type of cleaner but first I wanted to check with plumbers whether there is...

I have a question about the vacuum breakers that screw onto the hose spigot, I'm just curious how they work really. Are they 100% effective at keeping water from backflowing? Can a tiny amount of water get through before it closes off? I know how important they are. I just don't really...

I have an undersink water filter that has plastic tubing lines that jerk just a little when water has turned on or off in the house or yard, just so you hear them creak and you know water pressure has changed. Today I've been around the house all day and I have been hearing them doing that...

My plumber installed Uponor pex pipes in my utility room. My incoming water, shutoff, tankless WH and sediment filter are in this room whose door opens to the outdoors. This is a small space, more of a closet, really. I've been told I need to insulate the pipes because every time I open the door...

I have a Kohler Rialto that is working fine. I just wonder why, every so often, maybe once a month, I will go into the bathroom to wash my hands or put something away and I'll hear what sounds like a bubble come up in the toilet, just randomly. I've never been able to look over fast enough to...

I would like to install an access panel behind the shower wall, which would be in a walk-in closet, but I am curious since they don't seem to seal tight, do you get room air leaking in that would cause condensation on the pipes in the wall?

I have Zurn PEX with the old brass fittings, put in about 15 years ago. So far, no problems with it. But I have had some problems with galvanized fittings that are attached to it. For instance, galvanized threaded nipples threaded into the brass PEX fittings under sinks for the water supply...

I'm careful about keeping grease out of the drain but there is still some that gets washed down from residue on dishes and pots and pans and it seems to build up after time, especially in the garbage disposal. I just finished cleaning it all out and wondering where does all that stuff come from...

I'm asking for an elderly friend who has some health problems, is there a type of toilet plunger that doesn't take much physical strength to use?

The Uponor that connects to the line from my water heater is turning yellow. Is it normal for it to discolor from heat or is this a sign of trouble? It's a couple years old. I keep the water heater (tankless) at 125. You can see the normal color of the other line in the photo.

Is it unnecessary to put in an air gap for a dishwasher now? Does putting a high loop in the drain tube work just as well or is an air gap better?

I use this valve to bleed the system when I'm changing out filters but the space is too tight to get a bucket under it, so I'd like to add a short length of garden hose. Is there a fitting I can use to go from this PEX fitting to garden hose threads? I don't have the capability to do PEX.
