slow toilet leak

[scotty46]

It seems that the inside of the toilet bowl has a very slow leak. Is it a big deal to replace the rubber seal or is it best to take to the dealer?

Should have asked what make and model of toilet.

I second the motion for using silicone grease. Just make sure the seal and the knife blade are dry before applying a liberal amount of silicone grease to both. I have used this method for years and it saves a lot of work and expense.

Last time I looked the seal was around $10. Not hard to replace, just look at your toilet's owner's manual for directions. If its a decent quality dometic thats in good shape otherwise its usually worth the time to fix. If its an old plastic creaking special I always upgrade to a 310 or 320 model. Walmart sells the 310 for $199.99.

As said, a thorough cleaning is a good start. I've also used vinegar to flush as per a suggestion on here. It seemed to help,

I've yet to master the revitalization of flush ball seals, always had to replace them especially when the kids didn't understand the concept of keeping water in the bowl.

Before replacing clean the seal and lube it with plumbers silicone grease.. Don't use anything petroleum based!

Thetford toilets with the blade may only need to have the grove cleaned out.
