Part worked perfectly Thanks
John –
Found my endcaps slightly leaking when I replaced a circulation pump and thought this would be a bit more involved. Turns out it was pretty easy as well so thanks! Heads up for other DIY’ers, I tried hose clamps and what works far better is #4 rubber stoppers

Great got her fixed up thks

I’ve had my Grandee for 7 years, this was the first time I had a leak from my heater. I was about to order a complete heater, but found you had the end cap replacement which is all I needed. Thank you.
Marshall Wolfe (verified owner) –
Easy install.
Mike (verified owner) –
Perfect! Great website, great products, great delivery. Considered buying from other sites, but bought this with confidence. Will buy again from Backyardplus. Thanks!

Lasted 2 years with no much use, did have some temperature changes but hoped it would last longer
Elena –
Had a leak at the endcaps and figured I needed to replace the whole unit until I came by your part by accident. Easy to install and works great! Thanks
