The backup valve should shut off completely. All the pressure should be going to the Polaris for 3 minutes, and then all the pressure to the backup valve for 35 seconds. If water is coming out of the backup valve when it should be off, then needed pressure to the Polaris is being wasted.

If the Polaris is working fine, then no reason to fool with it. If not, you need to fix the backup unit. You can open it up and clean out debris and readjust it. (You'll really need a "strap wrench" from a hardware store to get off the outer ring. I paid $6). You can purchase the the inside mechanism if you can't fix it. You can also purchase an entire backup valve...outer case and inner mechanism. I bought one for $42 off ebay but they sell for $50-60 and my local pool store quoted $100.

Keeps loosing wifi signal

Try resetting your wireless router. Power cycle it through.

lost Internet access on all devices
unable to go online
no Internet connection on router
router Internet LED symbol is amber
To powercycle your home network:
Turn off the router by unplugging it. If you have a modem and router in one device, turn it off then proceed to step 3.
Turn off the DSL or cable modem for three minutes.
Note: Some modems are equipped with a backup battery. If your modem have one, please remove the backup battery to completely turn off your modem. For common cable modems equipped with backup batteries, please see Performing a full reset of cable modem with battery backup
Turn off all computers attached to your network.
Turn on the DSL or cable modem first and let it boot. Let it complete its connection to your ISP before proceeding to the next step. One of the indications that the modem have completed its connection is by seeing a green light on the modem. If you have a modem and router in one device, proceed to step 6 after it connects to your ISP.
Once the modem completes the connection to your ISP, plug in the router. Let it complete its power on test before proceeding to the next step.
Restart your computers.

Check the end of the steam wand for blockage, and or remove the tube feeding the valve and carefully turn machine on and run the steam cycle if no blockage, then remove wand and check for blockage.

Whats the best way to back up a laptop?

The best way probably depends on who you talk to. Microsoft includes there own backup programs in all versions except XP Home. (this version the backup is located on the original CD) I prefer to use Acronis. I use this personally and I have all my techs use use. Not only can we do normal backups but the program can do a complete image backup. That's to say if your hard drive went bad after doing a complete image backup then all you would have to do is replace the hard drive and then restore the image and you're back in business. Good luck

The Logo screen freezes on start up.

Connect it to your pc then turn it on. It should either connect or ask you to connect to the pc. If tt home opens shut it down. Do a complete backup of your unit onto the desktop. DO NOT USE TOMTOM HOME TO DO THIS!!!! After doing a complete backup format the drive on your tt useing fat 32. Open tt home and let it reload your os. Do this a couple of times to get the newest os. Disconnect your tt from the computer the way you normally do and restart your tt. Reconnect your tt and do not let home start. Go to your backup and copy and paste your maps back onto the root of your tt. If you have any question email me.
Hope this helps

Snapshot failure

Run the recommended chkdsk and backups still failed after completing the chkdsk w/o error. I than ran Spinrite on the disk which fixed a couple of disk problems. Then ran manual backup which completed without problem. Since the manual backup, the computer has backed up during the normal nightly backup without problem
