About a week ago the worn out old ballcock system broke on the toilet. My landlord picked up the LASCO 04-4059 kit: I went ahead and did the install as part of our rent-deal and the toilet now functions as it should but... runs constantly, specifically making a hissing gargling noise which it never did before. From what I can tell I followed the (terribly written) directions perfectly.
Today with some Googling I got pretty certain that the issue was that the new flapper wasn't forming a perfect seal. Cleaning the rim of where the new flapper sat made no difference, so I tested the seal with a piece of flat styrofoam and that seems to make a perfect seal.
Nonetheless the toilet still runs even with the seal and I do notice a slight bead of water sometimes along the side of the pump though that might be just a very occasional drip.
So I'm not sure if it's an issue with the pump or the float. Strangely if I tap the float or put my hand in the water and change the level the gargling stops for a little while. Adjusting the float level does control the water height but makes no difference with the noise.
Also I ran a test to see if I turned the water off at the valve at bedtime with the tank full whether it would be full in the morning. Strangely it was near empty in the morning which initially convinced me it was the flapper but now I'm not so sure. There was no standing puddle around the toilet in the morning either.
When I re-hooked the supply line I reassembled it as it had been prior and from what I can tell there's no evidence of a leak... no water on the floor around the line etc.
Assembling the supply line connection as previosly installed I did end up with these extra parts from the kit which are not mentioned anywhere in the directions.
As there's no evidence of a leak I don't know if they're extras or the source of the issue.
Frustrated too because as of this post I'm now at 2:30 on the 1-hour at $30/hour install deal with the landlord.
Any help appreciated. Thanks.
