Lowes has service.

Would Recommend

I was helped by an interested and alert guy who was in the aisle helping people. Sorry I don't remember his name, a Lowe's employee. I didn’t get this service any where else.

It worked with a minor modification.

Would Recommend

I had to use a separate rubber washer to make it seal, but once I did that it served its purpose until I could get a plumber to fix the leak.

do the job

Would Recommend

bought to seal an unused straddle valve and you need to apply lots of Teflon tape, otherwise it will leak. So far 3 days passed it worked.
