Not all state or municipalities require purple primer. Illinois if an inspector sees the purple primer it does not have to be pressured tested,but a lot of states you can use clear primer.
For the threads I use silicone grease. It helps seal but does not seize the threads.
I will not caulk the th toilet down unless it what the customer wants.
Caulking down a toilet will hide a leak. I would want the water to leak onto the floor then leak down to the next level. Cheaper to fix a seal than floor replacement.
The first cast iron (33"x22") sink I reinstalled is from 2005 with no problems. Still hanging in there.
Cleaning of both surfaces is what holds them together.
For your problem you may want to enhance the existing brackets by building another structure to help with the load.
It is not that easy. The whole sink has to be taken out to replace the silicone. It takes me around 4 to 6 hours to do this. Remove plumbing remove sink remove ALL old silicone. Double check ALL old silicone is removed. Build cradle to support weight of sink . Apply silicone and hang sink...
Yes. Cast iron sinks can and are held in place by silicone. Counter top guys usually install them but occasionally plumber do also.
I have reinstalled plenty of them. Silicone is a great adhesive and waterproofer.
Again you can always build a cradle to support the sink from underneath...
Stop tightening the bolts! All you are doing us pulling out the brass grommets that are epoxies into the countertop. The clamps are only there to hold the sink until the silicone set up. Silicone is the only thing holding the sink up. That is it.
If you feel the need to "fix" it build a wooden...
I promise you ,if you go to a plumber for a free cartridge you will make them laugh. The only way to get your free cartridge is directly from Moen.
If you xan spin the cartridge you have a chance of getting it out. The rubber gaskets will fight you the whole way and it will require a tool to...
Backup generator come in all different sizes. A 7kw with wifi is about $2000. You can have them automatically switch or manually again its all in how you want it to be. Obviously automatic is more expensive. I am not an electrician or salesman for the product. I am just a plumber.
You don't need a whole house generator. All you need is one large enough for the job.
And as for mechanical failure I've had more failures with backup systems then just Installing a second pump in the same crock (one submersible and one pedestal). How you spend your money is ultimately up to...
The battery back up pumps are incredibly expensive (yes $1500 is not out of line for the system). You get usually a boat bilge pump and all the parts one needs for backup system work.
You are far better off getting a backup generator
All of the drain methods that I have seen on this post are an air break. The suction is broken by air. If the sewer backs up it could siphon back to the dishwasher. An air gap requires a 1 inch gap of air. Most home centers sell a kit with an air gap, stainless steel hose clamps and 7/8 hose...
